The 150 will fly percect out of that bow. Cut it to 29.5"s and shoot it just as the other arrow, the regular insert and 160 grain head will give ya roughly 175 up front. I shoot them out of a Arroyo that is 54#s at my draw 28.5"s and cut them to 29.5" and add a 50 grain brass insert and 125 grain head and they fly perfect. I shot them out of a Silvertip that was 54#s as well with perfect flight, all done up if ya put on a wrap and 3 5" feather ya will be right around 500 grains. Shawn
