I would cut out and chisel a rock as a broadhead before I used a Rage! This afternoon is a glaring reason, and there are others as well, as to why I say that. A kid from down the street wanted me to check the tune of his bow and he wanted to check his arrow flight. He shot a few shots and everything was fine and he wanted to shoot a broadhead and I said go ahead. He pulled out this Rage tipped arrow and let it fly. Immediately the arrow started corkscrewing through the air and hit the target almost sideways....6inches right and 4inches high of where he was aiming. That flippin, stupid rubber-band broke and let the blades deploy in flight. I have seen this several times and had it happen to me years ago when they first came out...not to mention the penetration problems that so often plague mechanicals.
When they work, they do work well, but are you willing to risk wounding a deer, or ruining your chances of recovering a once in a lifetime deer? Stick with a fixed blade and you don't have to worry about moving parts failing.
