I really enjoy this topic. I always bought into the heavier the better b.s. up until about 4 years ago. Like someone else stated the correct arrow spine matched to the length of the arrow and the weight of the head is the key.
I have been shooting extremely light arrows 5.5 grains per inch at 29" with a 75 grain broadhead with a draw weight of 62 lbs.at 325 fps. I have taken my share of whitetails with this combination and never have I not got a complete pass thru.
