The tech at my local archery shop set me up with some new arrows for 3d. I am shooting 61 # martin bengal. They are carbon xpress 200 with 75 grain screw in points. Total arrow weight is 336 grains. I am shooting them at 288 fps. My question is that the lighter arrows make my bow sound louder. This weight is 5.5 grains per pound which is recomended. I am wondering if I should shoot a 100 grain tip or does that make a difference.
