I shot them last year and really liked them. I found them a PITA to pull out of targets, as they really do cut a very good spiral channel - if you get them, make sure you also buy some replacement blades as you will trash a couple ses of blades getting tuned to your bow - only downside I found while shooting these heads. I wasn't able to take a deer with them, though I'm told by the shop owner and a couple other customers there that they are pretty devastating heads.
