If you can do them pain free, try behind the neck presses. I do them as an assistance move on bench day (as opposed to overhead press day), at 50% of my training max for 5x10. For me currently, that's 85 pounds.
Why don't you like lateral raises? Doing those consistently after OHP has helped quite a bit. I'm using complexes though, designed for width - so they aren't quite as boring as just linear sets of raises. They kind of suck, but I get a good pump. Two examples:
1 - A. Seated lateral raises with the bench at 45 deg (still lowering and raising arms as straight up and down as possible) - 8-12 reps (full ROM)
B. Seated lateral raises with bench at 90 deg - 8-12 reps (full ROM)
C. Seated partial raises at 45 deg - 8-12+
D. Seated partial raises at 90 deg - 8-12+ (the plus depends on how you are feeling - I typically get about the same number of partials as I did full ROM reps)
A. Seated incline hybrid raise (bench at approx. 45 deg, movement somewhere between front and lateral raise) - 8-12 reps
B. Seated lateral raises (bench at 45 deg, lying face up same as previous complex) - 8-12
C. Standing lateral raise - 8-12
These two get a good burn and pump going. My delts stand out more since I started doing these and the behind the neck presses, compared to when I was just doing OHP and regular lateral raises.
