Thanks for the info. I guessI should have been a little clearer with my intentions. I am looking for good heads to use on Elk, Bear (Black and Brown),Moose, and Buffalo. While I don't have a lot of archery experience with all of these, I would tend to think it takes a head that is tougher than the hordes that work on deer. SoI guess my question should be revised to just that,which of these three are tough, sharp, and durable enough for those critters?
