OP, I already mentioned this in another thread but just in case you don't see it, you may want to hang on to the CSP a bit longer than just the 3 months to get the sign on bonus before the PC downgrade to Freedom. People have reported AA from doing that, as Chase doesn't enjoy people taking the $500 and running. It's been recommended that you hang on to the CSP for at least 6 months all the way up to the 1 year mark and bailing on it (downgrade) before the AF hits for the first time. With you having multiple Chase cards, I'd be very careful for things that could potentially stimulate AA.
