Yeah, I realize that they are to light. I've been playing around with the Stu Miller Calculator, but the only arrows that I have been able to get close have been either to light, around 7.1 gpp, or pretty heavy, around 11 gpp. I want a heavier arrow, but I don't want to sacrifice to much speed by shooting such a heavy arrow. It estimates that my arrows will fly at 168fps if I draw 29. I really don't know if that is considered fast or not. Any suggestions as to an arrow shaft to try?
