I recently was asked by a friend why I shoot feathers and not vanes? I couldn't answer this question because I always shot feathers and so did my father. I have noticed after watching the Pro's on TV and the guys on the ranges they use vanse some are as small as an Inch maybe and other around 3 inches. If i was to switch to vanes in the 3" how much of a difference would that make if im currently shooting 5" FEATHERS. Like more speed Kenitc energy things of that nature?
