wat53, post your specs as far as bow weight and type, draw length, etc.. and someone will be able to help you out. As far as the kids are concerned my younger daughter is shooting 1214 aluminums or 1/4" birch and raminwood with a 14# draw and my older daughters and wife shoot 1512, 1616, 1713 aluminums or 30-35# POC with 20-25# draws. They all like to make arrows and have fun trying different types and spines to see what works. Hope this helps, good luck....Shawn
PS: post a WTB ad on the arrow classifieds and it may turn up something
