I have skated on 1" and at times even less aggressive hollows for a long time. When people come into the shop and ask for 3/8" I always think they are nuts.
I think that the fit, the stiffness of the skates and the tightness of the laces has a big influence on how sharp the hollow feels for the skater.
A tight fitting and stiff skate will give you a sharper feeling than a loose fitting soft skate with the same hollow/profile.
I am 140lbs and use a 7/8" hollow. I feel I am one of the very few around here with a hollow that shallow as the guys who sharpen them always double check what I say. They always say "you mean 3/8"? I find deeper hollows fatiguing and my knees get sore.
