Hack squats (BB) are my favorite leg exercise, either flatfooted or heels raised on a 2" block. I will usually do GM'ings along with the Hacks, SS'ing at times. Think of BB Hacks as reverse DL's with more direction on the thigh/quads and less on the lower back & butt. Front squats are my second favorite leg exercise.
For TexR I might suggest dropping the regular squats for a while and do BB Hacks along with the GM'ings. You will probably find that the GM'ings will help greatly when you do finally go back to regular squating, as do heavy Hack squats. If your using wrapps for leg training than something is wrong with your form, style, rep scheme, etc. Wrapps are for set's of heavy 2's or three's on occasion, not for regular workouts unless you think your, or are, a power lifter.Also include some heavy abs work along with the leg training. This will help with future serious squating. The ab & lower back training is the cornerstone for any heavy leg work. Good Luck.
