Also be prepared to revane/fletch your arrows after about 15 passes through the biscuit. Someone recommended a drop of AEE adhesive at the leading edge of each vane to reduce the tearing factor. Have fun, the WB is very easy to shoot. I put it on my bow to get it set as a hand down to my son next year. The jury is still out if I will put another on my new bow..........sure do like that Parker UL31!!!!
