I like to try diferent mechanicals from year to year. Currently, I am on the Vortex bandwagon. Two blade version. What I like about these heads is they make a good entrance hole unlike most mechanicals. With the blades closed they still expose 1" of cutting surface. Entrance is close to the same size as the exit, a full 2" . In my opinion, a mechanical with a large cutting diameter is the perfect deal for thin skinned game like a deer.
