wanna hear something f**ked .... i could never press more than 100lb dumbells .... but i could easily crank out 10 reps incline flys with 75's or 80's (which is not far off from my incline press).
i dont know why this is .... and i was doing very strict flys with that weight (ie arms slightly bent but the angle doesnt change throughtout the movement and all the way down at the bottom) ..... coinsidently, all my presses with dumbells are done as fly presses(which is how most people do their flies)
100lb db'ls are nothing to sneeze at....most juicers I know dont go much over 120's - esp when they're off cycle.
Re the inclines, sounds like you maybe have strong front delts, or I think a lot of it comes down to skeletal structure which plays a big part in the leverage of any movement. Personally Im so bad at incline db presses that I dont even bother with them, but can use 3 plates a side for12 on incline barbell press...go figure....
Also - I know what you mean re fly presses. I used to do this type of action but got talked out of it by a pro. He said go super heavy for ur first excercise, eg flat DB or BB press, dont worry too much about form, just get em up. The following excercises like flyes and pullovers use good form.
This approach works really well (for me).
