Does anyone use feathers in the whisker bisquits? I have shot vanes through mine for a long time...noticed that the B2 fiber do help a little bit. I knew a guy at Fog Archery...15 minutes from my house...and he shot feathers through his bisquit all the time. He was a VERY good shot.(Shooting cigarette butts in his block from 40 yds) He swore that they flew better and less damage was done to feathers than to vanes in the long run. What do you guys think?
