I've had rotator cuff problems from way back (back to those days before you boys were born...

). I find that when I'm bench pressing (especially on the last couple of reps in a set), my form starts to slip some. When I don't pay strict attention to form, and maintain my elbows close to my sides, my shoulders hurt like a bugger for weeks following (cursor slaps himself upside the head and says, "don't do that!").
I have personally found the tight-elbows technique to make more of a difference in avoiding
shoulder injury than the limiting technique of not lowering the upper arm below horizontal.
Experiment and report back!
