Mr. Watkin's, The more hunter class shooters I talk to the more it seems that this rule should be addressed. What does the IBO have to say about theadvancement in fletching over the past few years and the rule of feathers or vanes no less than 4" allowed. It seems that over 90% of the hunters on TV use some type of short blazer type vane. Wouldn't you think that alot of hunters are switching to the short vanes also, especialy how well they do work. If many shooters use their hunting set-ups for IBO, I wonder how many have to change to 4" after hunting season and thenback to blazers oretc.for hunting season.A reply would be appreciated, Thanks Bob
