I'm having trouble keeping my vanes on. I'm shooting Easton Redlines with 1.87" Flex-fletch vanes. I'm continually losing vanes. Before fletching, I scarify the surface of the shaft with steel wool and then clean it with alcohol. I clean the base of the vane with acetone and then I use Bond-Tite to attach the vane. It's not a clearance problem, because it's never the same vane that comes off. Sometimes, it's the index vane and sometimes one of the hen vanes. HELP!!!
