The game trackers are a decent head, and I believe they will work well on deer for you. That said The Rocky Snypers are truely excellent. They are sharper, stronger, and open faster and with a rearward opening blades as opposed the the "jack knife" style of the first cuts. I belive this style of opening is more reliable and reduces any chance of the head "skipping" off an animal when the head opens. I will admint I really don't think the chances of deflection are that great with any head shot out of a well tuned bow, or at least my testing has shown it to not be a big problem.
