H80Hunter:

My emphasis was on "…don't be surprised IF….." I qualified my forewarning because you may not have any significant problems using a rest that is situated as to create an overdraw affect, and using shorter arrows.

I once used an "overdraw" (several months) that was positioned not too much further behind the riser than (probably) the WB is located. I was shooting 29" shafts, reduced from my normal 31-5/" inch shaft. I found the setup to be ultra-sensitive to hand-torque and nock-height tuning. My form and release had to be almost flawless. Under hunting conditions, the concern of the sensitivity of the setup constantly weighed on my mind. I found the constant concern to be a major mental distraction.

Knowing I was dumping the "overdraw," I never got deep into trying to find out why the setup was so sensitive. I simply blew it off as having something to do with the fact that the shaft resting too forward caused some type of misbalance with the arrow, and less string travel (brace) did not allow the shaft to start to stabilize before clearing the rest. Whatever the causes, I did not like an "overdraw." I have talked with other former "overdraw" users, and most did not like an "overdraw," either.

Here is a sample article that might better explain what may have caused some of MY problems with an "overdraw."
