hi there. i have all the tapes you mentioned except for ps legs and abs. body max is more of an endurance work out than strength because you do alot of fast reps as opposed to slow and steady. imo ithink the firm will work you out in a different way than cathe but that will be good for variety and muscle confusion. i am leaning more towards the body max tape mixed with ll and sl because mis has alot of the same moves as ll,but if floor work is important than ps legs and abs would be good becaus i have read from other posts that that tape has a very good floor section.
