Hey passthru, like Longbeard says, why use anything but a Muzzy, you can shoot curbs, probably penetrate steel I beams with the things, and still they are undamaged. I think anyone thatshoots any other brand must just be an idiot. Don't know why every other broadhead company doesn't just close up shop and go home right now. Personally I like the Wac'ems, but occassionally they do need sharpening/straightening and have absolutely no Kryptonite in them, so unlike the muzzy's, can't stop superman in his tracks.
