I love dumbbell shoulder presses (go as deep as you can), but I haven't done them lately because they do a number on my elbows. Face pulls or rear delt flyes are great for the rear delts, and you can't go wrong with side lateral raises for the side delts. I like doing side laterals one armed to take out any momentum.
I do front db raises cuz I can't press with a triceps tendon injury. Also lateral db raises and bent over db side raises. At 5 rep maxes for each of these I'm coming along pretty well. I would add military press but again the tendon so no pressing for a while.
