All will work fine, I have taken black bear on Theads, Zwickey, Magnus, Muzzy and Steelforce Premiums. A couple other to think about are the Magnus Stinger and Steelforce Premium 2-blade. After being a Muzzy fan, I switched to a cut on impact and don't regret doing so in the least. For me both heads fly great, right with my FP's. No worry about penitration with these suckers even with carbons and fast setups. Both are scary sharp out of the package, while the steelforce seem to hold the sharpness longer than the magnus, but both can be touched up on a lansky very easily for hunting season. Steelforce has awesome CS and will resharpen your used heads during the offseason at no charge. With Magnus I ran into supply issues but from what I have heard they didn't expect the demand to be so high on intial release of the stinger head and were basically caught with their pants down...supposedly that is now taken care of.
