Don't know if you were asking me or Akuma, but I'll respond with some advice.
Shoulders are pretty simple. You don't want to try to take the long way around with this bodypart. I realize that some people recommend power cleaning the barbell during shoulder workouts, and this was something oldschool bodybuilders did when equipment was minimal, but you will consistently find in bodybuilding that the guys with the best bodyparts always built them with the basic stuff.
The best chests are always built with barbell benching (Arnold, Ronnie, Branch, Franco), the best backs are always built with barbell rowing (Dorian, Ronnie, Haney), and similarly the best shoulders are always built with seated barbell presses and DB laterals (Ronnie, Branch, Levrone, Wheeler, Dorian, Ruhl... catch my drift?)
My entire shoulder routine consists of 4 sets of seated barbell presses (one heavy set 4-8, then one moderate set 8-12), 3 sets of DB side raises 10-15 reps (using the technique I've talked about on here before), and 3 sets of seated rear delt rows 12-15 reps. That's it. This routine is done twice each week.
Remember that there are no special exercises or training systems that work in place of balls-to-the-wall effort. If your shoulders lack size overall, just stick to the basics until you get good at them. Traditional exercises done with a full range of motion, frequently and with lots of repetition, is how 99% of guys built an impressive foundation of muscle mass.
