I think it is more to do with the strength you play at than any other factor. Now, I'm not the heaviest handed guy I know (I got a couple of friends that are pianists that sit in from time to time, and they always drive the G70 harder than I do!) but I still definitely come from a strong piano background, and am used to putting a lot more force into the note than players that perhaps came from organ, synth or accordion backgrounds.

All I know is, if it CAN move, I can make it move!
