I'd hit them on your chest day. That's what I do. I think flat and incline presses are the main builder of shoulder size. You could always try the highest incline you can use without it hurting as a main exercise if you do a seperate shoulder day.
Have you tried wide grip upright rows? If not have you tried upright rows in the smith machine with various width grips?
I'd start with side raises, I actually do mine half way between a side raise and a wide grip dumbbell upright row. A bit more of a "pull" movement than a raise. Let's you go heavy and still hit side delts hard.
Try doing ohp like this to finish, kind of gay but at least you can put some weights overhead without it being in a really taxing position: Larry Scott - Palm Out DB Press - YouTube
Oh yeah and try doing an upright row with the rope cable handle, you can adjust the height to find the best line of pull to hit delts hardest
