0% APR and Balance Transfers?

Don't know either card well, but I will tell you what I used to tell me financial counseling clients:

BEWARE THE FINE PRINT

If you accidentally make a purchase on the card with the 0% balance transfer, that purchase will accrue the going rate, whatever that will be. And of course any payments you make on the card will be applied toward teh 0% balance and not the higher rate balance. Yikes.

If you miss one payment, even by a matter of a day, your rate on the whole shebang will go through the roof. Bad.

If you miss a payment on something else in your credit report, the credit card companies might decide to nail you with universal default rates - bad.

Playing the "shell game" with credit cards can be beneficial, but you have to do it right. Some folks I know manage that well, but many don't.

And don't forget that opening lots of new accts is likely to adversely affect your credit score. Of course, this is a fairly minor consideration, especially if your credit history is already fairly robust.
