Wow, half inch plywood and they held together? I had heard the blades were weak, but thats a pretty good test of durability. Personally I switched to Sonic broadheads from Thunderheads a couple years ago, and they fly and shoot tremendously well. Somewhat small on the cutting diameter at 1", but a couple dead deer and elk in 2 years haven't seemed to notice that the cutting diameter was small. Let us know how the Crimson Talons perform on game.
