OP provided great tips. Worth also suggesting is to play around with the grip and understand that your grip for incline may very well differ than that for flat benching. I bring my grip out wide for incline, index on the rings, and retract my shoulder blades, and I feel very, very little stress on my front delts. It's virtually all chest. I also always suggest full ROM for this movement rather than cutting it short. Drop the weight you use and execute controlled reps. You may even find that using negatives on this exercise allows you to do more reps ... it does for me, which makes no sense.
