It is very simple speed does not matter period. Unversity of Wis Prof did a study. If you are shooting 200 FPS and a deer jump your string. The arrow would have to go over 700 fps to hit the deer. No matter if you shoot 200 or 300 the deer can still jump the string. Accuacy,Quiet, and enough Kentic energy are most important in my book.
BowTech Pro 40 240 fps 27 inch draw 430 grain arrow. All three deer last year had no idea what hit them. Tell your friend he is fine and to lighten up!!
