My tomkat came with the smooth cams and I had to take the fast mods to change my DL. I just noticed that the smooth mods broke over gradually and the fast cams have more of a certain point where they go over. I think if you're ego can handle it and you turn down your poundage, the difference gets smaller and less noticable.
About drawing, I don't feel much difference but when you draw down it kinda jerks.
I do prefer the fast mods but as Washington states, you could do better
with the smooth mods if times get colder and harsher.
