Need help choosing a new program

Okay, here goes! I started in may of last year doing Power 90. Completed my 90 days, never skipped a day, did awesome & lost 25 pounds. Then I went on to Power 90 Master Series. Liked it. Finished it. Lost an additional 5 pounds. Kept on doing it through the Christmas holidays. Gained a few pounds back.
On January 2nd, I started P90X. It's okay. It's not too hard, but it's not too easy either. But I'm not progressing. I am not eating perfect. But I'm not eating horrible. And I have gained weight. I DON'T like that. I'm thinking perhaps this is not the program for me. I'm 5'7", 44 years old, and within my weight range. But I'd still like to be 15 pounds thinner. I want to look lean, and I don't like the bat wings I'm developing from the pullups.
Maybe Slim in 6? Or will that be too easy?
Turbo Jam or Fire (not super coordinated, though)?
HELP PLEASE!
