Go down to Lowes, pickup 12 3/8 inch poplar dowels with straight grain and that feel around the same stiffness. Taper the last 12 inches and put a 5/16 point on em cut your string groove and fletch. its unbeleivable but these things will fly great and straight from a 20lb bow to a 70lb bow. And the dowels are like less than a dollar each, or atmost 1.10. Goodluck, and I hope you try it.
