I was wondering what, if any, changes I should make to my routine to spurt greater myofibrillar hypertrophy. I would prefer to be a powerbuilder...one with great strength, but also look aesthetically built as well. Here's what I do now:

Chest/Triceps
6 sets bench - 3 reps per set 1 day and the next 6 reps the next
4 sets weighted dips - usually 8 reps
4 sets either CGBP or skull-crushers on decline. 6-8 reps

Back/Biceps
4 sets deadlifts - 3-4 reps one day and next 6-8
4 sets weighted pullups - alternate weeks with mix grip, traditional, and
hammer. Usually 6-8 reps
4 sets either single arm DB rows or bent over BB rows - usually 8 reps
4 sets spider curls (alternate bicep exercises every 4 weeks) - 8 reps

Shoulder/Chest
6 sets dumbell bench - 8 reps. Thinking of alternating hi/low day
4 sets military or dumbell press - 8 reps
4 sets laterals or lying laterals - 8-12 reps

Squat
4 sets squat - 6 reps. Go just below parallel, it hurts my right knee when I go ATG
2 sets front squat
4 sets step ups - 6 reps

Speed Bench
10 sets - 3 reps

I lift one day, followed by cardio (boxing and jumping rope) the next. So lifting is every other day. I also just purchased some flex bands, so if someone could tell me how to incorporate those I would be much obliged.
Also, could someone recommend a good rep scheme for deadlift? I want to shock my routine up a bit to fight stagnation. Thanks a lot
