Working through my first churn today...I'd like to try for 4 cards. Trying to stay away from Chase cards (even though I'd love to get a Sapphire!) I applied for Citi Hilton Honors for 40k and Delta Suntrust 5k Checking so far. I'd like to get some AMEX Membership rewards points. I currently do not have any of those cards. I already have Chase Continental and Starwood/Hilton Amex. I have excellent credit to work with. Any suggestions? What's the best bang for my buck out there right now?
