I'm curious as to what arrow Iceman shooters are using.

I'm using a Blackhawk Vapor Pro 4000 (pre Gold Tip ownership) and it seems like it is too weak a spine when I shoot bare shafts at 20 yards (hits to the right). I have cranked it down from 70# to 65# and while it improved some, it still isn't what I want. I shooting a 29.5" arrow with a 100 gr point. I would rather switch out arrows than go up to a 125 gr tip.
