I shot Thunderheads for many years and then switched to Muzzy and now I'm shooting Montec. All three were excellent heads and all three killed deer. I'm now most impressed by the Montecs but thats just my opinion. I'm sure there are many other good B-heads out there that I have not had the opportunity to shoot that will perform very well. About Best???, If there was one B-head that out performed all others we would all be shooting them. There is so much information available today about performance that we find out about the bad ones soon after they are introduced to the market. The good ones have weathered the test of time. Pick one of the proven heads and go with it. For me it's Montec for now.
