Hmm...I dont agree with you on 20 reps for growth I must say.

Im sure a noobie would grow with it, but it's not sustainable. I would use that kind of workout for endurance/fat loss.
I grow best with low reps, high weights and lots of good calories and rest.

check it out man. http://www.ironworkout.com/20_rep_squat.htm for some reason 20 is the magic number for rapid growth.

there is a book on this too I have it somewhere. It's called Super Squats. this article was just the first thing that came up when i googled it.
