Cut on contacts are great. I shoot a very high KE so I am able to get away with muzzies but would tell anyone that cut on contact are best. The shots are generally very close so I would concentrate on a heavier arrow than I would speed. I shoot Hoyt Protec at 70 lbs with a 29.5 inchdraw. I am using Easton super slams this year that are 2413's. I am like GS in the fact that I like a higher FOC for hunting.
