As far as mechanicals go I have shot Steelheads, Spitfires, Tekans, and Rage on deer. All of them performed well, but I always end up coming back to a fixed blade head. I like the k.i.s.s. approach. This year I am going to try the G5 Strikers. If you are dead set on shooting mechanicals, I would suggest this Tekans or the Rage heads.
