Patent isn't the issue as the Shockwave has a chisel tip. Personally,I would never shoot a mechanical that didn't have at least a chisel tip or coc but I only shoot 57# so I'm pretty much over the mechanical head phase and shoot coc exclusively. Might even go with a helix single bevel if I ever decide to head out your way Dubbya.
Well I shoot 70#, 28.5" draw and a 450gr arrow...I don't think I would have any issues with penetration using either head. I have used Thunderheads for many years and have come to trust the Trophy Tip. So I figured why screw with a good thing...I'll just keep using the same tip. Maybe I will pick up a pack of the CoC and give them a shot this upcoming deer season.
