I think there is a setback to everything you use to hunt with in archery hunting to some people.I have lost one animal with the mech. heads .I found they tend to glance off your target if you shoot at an angling away shot but nothing is for sure in archery hunting, a limb or a twig causes me more problems than worring about the heads I use.My self I use good old wasps 125 heads .But nothing is a sure thing.Just have fun and be safe I say.
