I shoot Muzzy three blade 125s on my hunting bow and I shoot NAP Spitfires on my crossbow. every dead deer will agree they work in both scenarios. Its a matter of what shoots best on your bow. Muzzys might not hit your field point holes but tune the bow to Muzzys with practice blades and shhot those. I can tell you that muzzys lose about 3 grs in weight per 200 shots. I weigh my broadheads and arrows and match light heads with heavy arrows and visa versa keeps em all tight on the target. An inexpensive reloading scale is priceless for setup.
