I can lean forward on mine pretty easily. Just do a push up! I can get some sit up straighter by shifting to light contact with the bar. And on 20 mile rides where I do that, my wrists don't complain. Problems kick in when I'm nervous about navigating, or I'm nervous about the terrain.

Probably what I should do is go test ride some other bikes with different bars to get a clearer idea of what works for me.
