Ken,
Jim from JJT Outdoor Sports here with an equipment question. We carry AAE Plastifletch vanes - 4" , however, after setting a guy up at the shop, we measured these vanes and they' re actually 3 7/8" ......so how does this work for HC??? Manufacturer markets at 4" and is actually short???

I' m concerned because we mainly use these vanes at the shop.

Thanks,
Jim
