What is the preferred mix of credit cards?

I have:

3 Credit Union Visas totalling $20,000

1 BoA Amex toatalling $15,000

Do I need or should I have any other cards?

10% of your FICO score deals with the types or rather mix of credit types used.

Here's from the Credit Education tab above:

Types of Credit Used

• Number of (presence, prevalence, and recent information on) various types of accounts (credit cards, retail accounts, installment loans, mortgage, consumer finance accounts, etc.)

...

FICO doesn't care which card types you have; they only want to see that you have a store card, revolving card or installment loan, etc. If you don't have a store card, it may be good to have one (non-visa card)
