Rev, I wholeheartely agree that shooting a fixed blade in windy conditions may or could cause erratic arrow flight or cause an arrow to veer off course. But Could not the same be said for wind catching the fletching?
I know there are times when we are not hunting in ideal conditions (wind, rain, excessive heat) but under normal shooting conditions at yardages 40 yds and less with no wind or slight breeze, the average shooter should find no discernable POI difference between a FT and BH out of a proberly tuned bow. Wouldn't you agree?
