i use 100 grn muzzys and they do quite well...every deer ive shot was a compleate pass through and the didnt go much over 75 yards...it all works together, the weight of arrow
the spline the head and weight forward...you find what works best for your bow simple as that,no one can tell how your bow will shoot with anykind of head untill youve done it.if your happy useing what you use by all means stick with it...your takeing the shot not anyone else..good hunting and good luck,,,
