KEY INFORMATION

WHAT ARE THE FUND'S GOALS?

The STRONG ADVANTAGE FUND seeks current income with a very low degree of
share-price fluctuation.

WHAT ARE THE FUND'S PRINCIPAL INVESTMENT STRATEGIES?

The ADVANTAGE FUND invests primarily in very short-term, corporate, and
mortgage- and asset-backed bonds. The fund invests primarily in higher- and
medium-quality bonds. To enhance its return potential, the fund also invests a
portion of its assets in bonds that have longer maturities or are of
lower-quality (high-yield or junk bonds), though it may not invest in bonds
rated below BB.  The managers focus upon high-yield bonds rated BB with
positive or improving credit fundamentals. To help limit changes in share
price, the fund's average maturity is usually one year or less.

The managers may sell a holding if its value becomes unattractive.  Also, the
managers may invest any amount in cash or cash-type securities as a temporary
defensive position to avoid losses during adverse market conditions.  This
could reduce the benefit to the fund if the market goes up.  In this case, the
fund may not achieve its investment goal.  The fund was designed for investors
who seek higher yields than those generally offered by money market funds and
who are willing to accept some modest share-price fluctuation to achieve that
objective.

WHAT ARE THE MAIN RISKS OF INVESTING IN THE FUND?

BOND RISKS: The major risks of the fund are those of investing in the bond
market. A bond's market value is affected significantly by changes in interest
rates-generally, when interest rates rise, the bond's market value declines and
when interest rates decline, its market value rises (interest-rate risk).
Generally, the longer a bond's maturity, the greater the risk and the higher
its yield. Conversely, the shorter a bond's maturity, the lower the risk and
the lower its yield (maturity risk). A bond's value can also be affected by
changes in the bond's credit-quality rating or its issuer's financial condition
(credit-quality risk). Because bond values fluctuate, the fund's share price
fluctuates. So, when you sell your investment, you may receive more or less
money than you originally invested.

HIGH-YIELD BONDS: The fund invests a limited portion of its assets in medium-
and lower-quality bonds, including high-yield bonds (commonly referred to as
junk bonds). Lower-quality bonds involve greater interest-rate and
credit-quality risks than higher- and medium-quality bonds. High-yield bonds
possess an increased possibility that the bond's issuer may not be able to make
its payments of interest and principal. If that happens, the fund's share price
would decrease and its income distributions would be reduced.  An economic
downturn or period of rising interest rates could adversely affect the
high-yield bond market and reduce the fund's ability to sell its high-yield
bonds (liquidity risk).  A lack of a liquid market for these bonds could
decrease the fund's share price.

FOREIGN SECURITIES: The fund may invest up to 25% of its assets in foreign
securities.  Foreign investments involve additional risks including
currency-rate fluctuations, political and economic instability, differences in
financial reporting standards, and less-strict regulation of securities
markets.

MORTGAGE- AND ASSET-BACKED SECURITIES: The fund invests in mortgage-backed and
asset-backed securities.  These securities are subject to prepayment risk,
which is the risk that the borrower will prepay some or all of the principal
owed to the issuer. If that happens, the fund may have to replace the security
by investing the proceeds in a less attractive security.  This could reduce the
fund's share price and its income distributions.

The share price of the fund will vary.  The fund is not appropriate for
investors concerned primarily with principal stability.

FUND STRUCTURE
The fund offers multiple classes of shares:  Investor Class shares,
Institutional Class shares, and Advisor Class shares.  Only the Advisor Class
shares are offered in this prospectus.  The principal difference between each
of the classes of shares is that the Advisor Class shares are subject to
distribution fees and expenses under a 12b-1 plan and that each class of shares
is subject to different administrative and transfer agency fees and expenses.

FUND PERFORMANCE
The return information on the next page illustrates how the performance of the
fund's Advisor Class shares can vary, which is one indication of the risks of
investing in the fund. Performance results for Advisor Class shares, which were
first offered on August 31, 1999, are based on the historical performance of
the Investor Class shares from the inception of the fund up to August 30, 1999,
recalculated to reflect the higher annual expense ratio applicable to the
Advisor Class shares.  The Investor Class shares are not offered by this
prospectus. The returns for the Advisor Class are substantially similar to
those of the Investor Class shares since each are invested in the same
portfolio of securities and the only differences relate to the differences in
the fees and expenses of each class of shares. Please keep in mind that the
past performance of the fund's Advisor Class shares does not represent how it
will perform in the future.  The information assumes that you reinvested all
dividends and distributions.

<PAGE>

This section describes the fees and expenses that you may pay if you buy and
hold shares of the fund.

SHAREHOLDER FEES
(fees paid directly from your investment)
All of the Strong Funds are 100% no-load, so you pay no sales charges (loads)
to buy or sell shares.

ANNUAL FUND OPERATING EXPENSES
(expenses that are deducted from fund assets)
The costs of operating the fund is deducted from fund assets, which means you
pay them indirectly. These costs are deducted before computing the daily share
price or making distributions. As a result, they don't appear on your account
statement, but instead reduce the total return you receive from your fund
investment.

OTHER IMPORTANT INFORMATION YOU SHOULD KNOW

A WORD ABOUT CREDIT QUALITY

CREDIT QUALITY measures the issuer's expected ability to pay interest and
principal payments on time.  Credit quality can be "higher-quality",
"medium-quality", "lower-quality", or "in default".

HIGHER-QUALITY means bonds that are in any of the three highest rating
categories.  For example, bonds rated AAA to A by Standard & Poor's Ratings
Group (S&P)*.

MEDIUM-QUALITY means bonds that are in the fourth-highest rating category.  For
example, bonds rated BBB by S&P*.

LOWER-QUALITY means bonds that are below the fourth-highest rating category.
They are also known as non-investment, high-risk, high-yield, or "junk bonds".
For example, bonds rated BB to C by S&P*.

IN DEFAULT means the bond's issuer has not paid principal or interest on time.

* OR THOSE RATED IN THIS CATEGORY BY ANY NATIONALLY RECOGNIZED STATISTICAL
RATING ORGANIZATION.  S&P IS ONLY ONE EXAMPLE OF A NATIONALLY RECOGNIZED
STATISTICAL RATING ORGANIZATION.

This chart shows S&P's definition and ratings group for credit quality.  Other
rating organizations use similar definitions.

</TABLE>

We determine a bond's credit quality rating at the time of investment by
conducting credit research and analysis and by relying on credit ratings of
several nationally recognized statistical rating organizations.  These
organizations are called NRSROs. When we determine if a bond is in a specific
category, we may use the highest rating assigned to it by any NRSRO. If a bond
is not rated, we rely on our credit research and analysis to rate the bond.  If
a bond's credit-quality rating is downgraded after our investment, we monitor
the situation to decide if we need to take any action such as selling the bond.

Also, investments in lower-quality bonds (junk bonds) will be more dependent on
our credit analysis than would be higher-quality bonds because, while
lower-quality bonds generally offer higher yields than higher-quality bonds
with similar maturities, lower-quality bonds involve greater risks.  These
include the possibility of default or bankruptcy because the issuer's capacity
to pay interest and repay principal is considered predominantly speculative.
Also, lower-quality bonds are less liquid, meaning that they may be harder to
sell than bonds of higher quality

                                       6
<PAGE>

because the demand for them may be lower and there are fewer potential buyers.
This lack of  liquidity may lower the value of the fund and your investment.

FINANCIAL HIGHLIGHTS

This information describes investment performance of the Investor Class shares
of the fund for the periods shown. Certain information reflects financial
results for a single Investor Class share.  "Total Return" shows how much an
investment in the Investor Class shares of the fund would have increased (or
decreased) during each period, assuming you had reinvested all dividends and
distributions. The Advisor Class shares of the fund were first offered on
August 31, 1999.  These figures for the fund have been audited by
PricewaterhouseCoopers LLP, whose report, along with the fund's financial

YOUR ACCOUNT

All of the Strong Funds are 100% no-load.  This means that you may purchase,
redeem, or exchange shares directly at their net asset value without paying a
sales charge.

DISTRIBUTION FEES

The Strong Funds have adopted a Rule 12b-1 distribution plan for the Advisor
Class shares of the fund.  Under the distribution plan, the fund may make
monthly payments to the funds' distributor at the annual rate of 1.00% of the
average daily net assets of the fund attributable to its Advisor Class shares.
However, under the Distribution Agreement for the Advisor Class shares,
payments to the fund's distributor under the distribution plan are currently
limited to payment at an annual rate equal to 0.25% of average daily net assets
attributable to Advisor Class shares.  Such payments may be made for
distribution related services and other services which are primarily intended
to result in the sale of Advisor Class shares of the fund.  Because Rule 12b-1
fees are on-going, over time they will increase the cost of an investment in
the Advisor Class shares of the fund and may cost more than other types of
sales charges.

SHARE PRICE

Your transaction price for buying, selling, or exchanging Advisor Class shares
is the net asset value per share (NAV) of that class of shares.  NAV is
generally calculated as of the close of trading on the New York Stock Exchange
(usually 3:00 p.m. Central Time) every day the NYSE is open.  If the NYSE
closes at any other time, or if an emergency exists, NAV may be calculated at a
different time.  Your share price will be the next NAV calculated after we
accept your order.

NAV is based on the market value of the securities in a fund's portfolio.  If
market prices are not available, NAV is based on a security's fair value as
determined in good faith by us under the supervision of the Board of Directors
of the Strong Funds.

FOREIGN SECURITIES
Some of the fund's portfolio securities may be listed on foreign exchanges that
trade on days when we do not calculate an NAV.  As a result, the fund's NAV may
change on days when you will not be able to purchase or redeem shares.  In
addition, a foreign exchange may not value its listed securities at the same
time that we calculate the fund's NAV.  Events affecting the values of
portfolio securities that occur between the time a foreign exchange assigns a
price to the portfolio securities and the time when we calculate the fund's NAV
generally will not be reflected in the fund's NAV.  These events will be
reflected in the fund's NAV when we, under the supervision of the Board of
Directors of the Strong Funds, determine that they would have a material effect
on the fund's NAV.

of shares in the class outstanding.

alliance partners provides administrative services, there is no initial

The fund has adopted a multiple class plan which currently permits it to offer
three classes of shares:  Investor Class shares, Institutional Class shares,
and Advisor Class shares.  Each class is offered at its net asset value without
the imposition of any sales load, however, each class of shares is subject to
fees and expenses which may differ. The principal difference between each of
the classes of shares is that the Advisor Class shares are subject to
distribution fees and expenses under a 12b-1 plan and that each class of shares
is subject to different administrative and transfer agency fees and expenses.

 BUYING INSTRUCTIONS

 Sign up for the exchange option when you open your account. You may exchange
 your shares of the fund for shares of another Strong Fund.  You may make an
 exchange by calling Strong Institutional Client Services at 1-800-368-1683 or
 by sending a facsimile to 1-414-359-3535.  Please obtain and read the
 appropriate prospectus before investing in any of the Strong Funds.  Remember,
 an exchange of shares of one Strong Fund for those of another Strong Fund, is
 considered a sale and a purchase of fund shares for tax purposes and may
 result in a capital gain or loss.  Some Strong Funds that you may want to
 exchange into may charge a redemption fee of 0.50% to 1.00% on the sale of
 shares held for less than six months.  Purchases by exchange are subject to
 the investment requirements and other criteria of the fund purchased.

 WIRE
 Call 1-800-368-1683 for instructions before wiring funds either to open or add
 to an account.  This helps to ensure that your account will be credited
 promptly and correctly.

 BROKER-DEALER
 You may purchase shares through a broker-dealer or other intermediary who may
 charge you a fee.

 PLEASE REMEMBER . . .
- - Make checks or money orders payable to Strong Funds.

- - We do not accept cash, third-party checks (checks payable to you written by
  another party), credit card convenience checks, or checks drawn on banks
  outside the U.S.

- - You will be charged $20 for every check, money order, wire, or Electronic
  Funds Transfer returned unpaid.

 SELLING SHARES

 You can access the money in your account by selling (also called redeeming)
 some or all of your shares by one of the methods below.  After your redemption
 request is accepted, we normally send you the proceeds on the next business
 day.

 SELLING INSTRUCTIONS
 You can sell shares in several ways.

 MAIL
 Write a letter of instruction.  It should specify your account number, the
 dollar amount or number of shares you wish to redeem, the names and signatures
 of the owners (or other authorized persons), and your mailing address.  Then,
 mail it to the address listed on the back of this prospectus.

 REDEMPTION OPTION
 Sign up for the redemption option when you open your account.  With this
 option, you may sell shares by phone and receive the proceeds in one of three
 ways:

  (1)     We can mail a check to your account's address.  Checks will not be
 forwarded by the Postal Service, so please notify us if your address has
 changed.

  (2)     We can transmit the proceeds by Electronic Funds Transfer to a
 properly pre-authorized bank account. The proceeds usually will arrive at your
 bank two banking days after we process your redemption.

  (3)     For a $10 fee, we can transmit the proceeds by wire to a properly
 pre-authorized bank account. The proceeds usually will arrive at your bank the
 first banking day after we process your redemption.

 BROKER-DEALER
 You may sell shares through a broker-dealer or other intermediary who may
 charge you a fee.

 PLEASE REMEMBER ...
- - If you recently purchased shares, a redemption request on those shares will
  not be honored until 10 days after we receive the purchase check or
  electronic transaction.
- - Some transactions and requests require a signature guarantee.
- - With an IRA (or other retirement account), you will be charged (1) a $10
  annual account maintenance fee for each account up to a maximum of $30 and
  (2) a $10 fee for transferring assets to another custodian or for closing an
  account.
- - If you sell shares out of a non-IRA retirement account and you are eligible
  to roll the sale proceeds into another retirement plan, we will withhold for
  federal income tax purposes a portion of the sale proceeds unless you
  transfer all of the proceeds to an eligible retirement plan.

SIGNATURE GUARANTEES help ensure that major
transactions or changes to your account are in fact
authorized by you. For example, we require a
signature guarantee on written redemption requests
for more than $50,000.  You can obtain a signature
guarantee for a nominal fee from most banks,
brokerage firms, and other financial institutions.
A notary public stamp or seal cannot be substituted
for a signature guarantee.

 ADDITIONAL POLICIES

 TELEPHONE TRANSACTIONS
 Once you place a telephone transaction request, it cannot be canceled or
 modified. We use reasonable procedures to confirm that telephone transaction
 requests are genuine.  We may be responsible if we do not follow these
 procedures.  You are responsible for losses resulting from fraudulent or
 unauthorized instructions received over the telephone, provided we reasonably
 believe the instructions were genuine. During times of unusual market
 activity, our phones may be busy and you may experience a delay placing a
 telephone request.

 DISTRIBUTIONS

 DISTRIBUTION POLICY
 The fund generally pays you dividends from net investment income monthly and
 distributes any net capital gains that it realizes annually.  Dividends are
 declared on each day NAV is calculated, except for bank holidays. Dividends
 earned on weekends, holidays, and days when the fund's NAV is not calculated
 are declared on the first day preceding these days that the fund's NAV is
 calculated.  Your investment generally earns dividends from the first business
 day after we accept your purchase order.

 REINVESTMENT OF DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS
 Your dividends and capital gain distributions will be automatically reinvested
 in additional shares, unless you choose otherwise.  Your other options are to
 receive checks for these payments, have them automatically invested in another
 Strong Fund, or have them deposited into your bank account. To change the
 current option for payment of dividends and capital gains distributions,
 please call 1-800-368-1683.

 TAXES

 TAXABLE DISTRIBUTIONS
 Any net investment income and net short-term capital gain distributions you
 receive are taxable as ordinary dividend income at your income tax rate.
 Distributions of net capital gains are generally taxable as long-term capital
 gains.  This is generally true no matter how long you have owned your shares
 and whether you reinvest your distributions or take them in cash. You may also
 have to pay taxes when you exchange or sell shares if your shares have
 increased in value since you bought them.

 RETURN OF CAPITAL
 If your fund's (1) income distributions exceed its net investment income and
 net short-term capital gains or (2) capital gain distributions exceed its net
 capital gains in any year, all or a portion of those distributions may be
 treated as a return of capital to you. Although a return of capital is not
 taxed, it will reduce the cost basis of your shares.

 YEAR-END STATEMENT
 To assist you in tax preparation, after the end of each calendar year, we send
 you a statement of your fund's ordinary dividends and net capital gain
 distributions (Form 1099).

 BACKUP WITHHOLDING

                                      12
<PAGE>

 By law, we must withhold 31% of your distributions and proceeds if (1) you are
 subject to backup withholding or (2) you have not provided us with complete
 and correct taxpayer information such as your Social Security Number (SSN) or
 Tax Identification Number (TIN).

<TABLE>

COST BASIS is the amount that you paid for the
shares. When you sell shares, you subtract the cost
basis from the sale proceeds to determine whether
you realized an investment gain or loss.   For
example, if you bought a share of the fund at $10
and you sold it two years later at $11, your cost
basis on the share is $10 and your gain is $1.

 Because everyone's tax situation is unique, you should consult your tax
 professional for assistance.

 RESERVED RIGHTS

 We reserve the right to:

- - Refuse, change, discontinue, or temporarily suspend account services,
  including purchase, exchange, or telephone redemption privileges, for any
  reason.

- - Reject any purchase request for any reason including exchanges from other
  Strong Funds.  Generally, we do this if the purchase or exchange is
  disruptive to the efficient management of the fund (due to the timing of the
  investment or an investor's history of excessive trading).

- - Change the minimum or maximum investment amounts.

- - Delay sending out redemption proceeds for up to seven days (this generally
  only applies to very large redemptions without notice, excessive trading, or
  during unusual market conditions).

- - Suspend redemptions or postpone payments when the NYSE is closed for any
  reason other than its usual weekend or holiday closings, when trading is
  restricted by the SEC, or under any emergency circumstances.

- - Make a redemption-in-kind (a payment in portfolio securities rather than
  cash) if the amount you are redeeming is in excess of the lesser of (1)
  $250,000 or (2) 1% of the fund's assets. Generally, redemption-in-kind is
  used when large redemption requests may cause harm to the fund and its
  shareholders.  This includes redemptions made by checkwriting.

- - Close any account that does not meet minimum investment requirements.  We
  will give you notice and 60 days to begin an automatic investment program or
  to increase your balance to the required minimum.

- - Reject any purchase or redemption request that does not contain all required
  documentation.
