My spouse and I are about to max out the the MQM bonuses on two Delta Reserve AMEX cards. (And I'll make Plat on Delta with plenty of rollover miles for next year as a result -- I run a lot of business expenses through these cards.) Most of my spending is done for the year, but I have at least another $10K to spend this year, maybe $15K. Right now, I'm thinking about getting the Hilton Visa that comes with two free nights and also getting the free Hilton AMEX later to give me access to the AXON awards for my existing Hilton points, mostly earned through actual stays as it is my chain of choice on business travel.

Any other suggestions on what new card to get with $10K to 15K in spend for hopefully a large sign up bonus? By the way, because I'm in Atlanta, I'm not interested in specifically branded airline cards for an airline other than Delta.
