I agree with the 10 grains of arrow weightper pound, those arrows shoot plenty flat and you shouldnt have any problem getting your bow to shut up. Its also my opinion that anything to much over 12 grains per pound(13+) is unnecessary in 95% of hunting situations stick right around the 9-12 Grains per # of pull wieght and youll be happy.

Do what you have toin orderto get good Flight with The shafts you have tho.
