No idea about this rap. Took two deer with double lung shots with the Montecs this year. Blew blood everywhere. Both dropped within 50 yards. Did nothing more than run them acrosstheG5 stone that I purchased with them. Seem pretty sharp to me. Been said a hundred times, it's all about shot placement. There was a fella posted here he put a target tip through a deer once. Not advocating that, but I believe him. All this "razor sharpness" is another arguement I can't understand when we're flinging arrows 300fps.I like the doctors scapel comparrisons. Like a broadhead traveling at300fps needs to be as sharp as sombody cutting out a tumor in your brain. Makes for good posts and conversation I guess.
