Rod is right. My wife is an excellent barebow shooter, and shoots longbows at her 24" draw length. On her 64" 37# @ 28" Chaparral, she shoots 1516 or 1616 Eastons with NIBB target points. With her 40# 64" Dryad longbow, she shoots only 1616 Easton, or sitka spruce & POC wood, spined 25-30, and cut to 26", with a 70g point.
There is no way she can work with carbon at those light weights, and short draw length, and shoot at the distances required in 3-D & also field shooting. Bill G.
