Any technique you choose works if you fallow all their principles write. Heavy Duty, Super Slow, Traditional training, volume, HIT, Dog crap, Victor Munoz, training, Charles Glass training.... they all end in just do it!!!!
Milos Giant Sets technique is good, off season or show prep, muscle stimulation is the name of the game and like A50 sayd, it is a matter of diet to grow or get ripped.
You can get injured anyway easy bc the intensity and muscle failure.
