Top shoulder girdle builder's, in my view, are push or jerk presses off a rack. Get to handle huge weight with huge results after awhile. The one arm side DB press, not to be confused with regular DB press, is another great dellt exercise. Also try DB upright rows, one arm at a time, rather that the rgular BB version. Some find less stress on the joints themselves with a DB. PBN and bent arm laterial raises are two other mass builders.
Sorry to disagree, but the press is not basically the same as the front raise. The press is a pushing compound movement. The front raise (as laterial raises) is an extension movement (weight lifted out and away from the body). In either case the position of the elbows makes the difference. If you want top potental mass, and rather fast, than select the compound press. If you can not build anterio/laterial delts from pressing exercises (BP, inclines, military press, etc) than something is wrong with your basic body structure. Or you are overworking those muscles and not allowing enought time for recovery.
Really no need to do front raises, unless you get overwhelmed with joy by the short lived pump you may get. A pump does not always mean growth. Good Luck.
