If you are planning on competing then a program that will allow you to stay in your weight class but get as strong as possible will be paramount then.
As for @fit I know that they're previous biggest proponent, BJ Penn stopped using it and started winning.
Seriously though, if you need to focus on getting stronger in a certain movement then @fit probably isn't your best bet. I'd do something along the lines one of Dos's strength programs from his book - there you get a serious strength program with power work included. He also has some great conditioning to throw in there, such as leg matrixes and the like.
His collegiate athletes use 'em.
Brief workouts with mostly low reps focusing on compound and explosive lifts.
You likely get alot of conditioning work in MMA training of course - which may be why it's your strong point
