As with anything there is a point of dimished returns As of yet I have not found that point:p 1 set of my arrows have an FOC of 24% and another set has 38%, Both sets fly great with the 38% having more penetration and a lot less wind drift.
Joe I was actually going to buy a FP test kit from 3R. I was telling one of my friends last night and he wants me to look at his set-up to see if we can do something for him. I might as well just get one. Thanks though.
