How does this look for building strong, big legs?

Squats
4 sets of 20,20,15,15 (The higher rep squats seem to work better for me as a mass builder)

Hack Squats
3 sets of 10,10,10

Leg A**uctor
3 sets of 12,12,12 (Not going too too heavy cuz can cause injury)

Lying Leg Curls
3 sets of 10,8,6 (go heavy)

Standing Calf Raise
3 sets of 20,20,20 (Go heavy with feet pointed outwards)

Leg Press Calf Raise
2 sets of 8,6


Just wanted to see if this seemed good and if anyone had any advice they wanted to throw in about leg workouts.

Thanks.
