Has anyone used either of these heads and which do you prefer? I like the 2 inch cut by the hypershocks and the chisel tip point, but am concerned about the small entrance hole-especially when there is no pass through. With the snypers, i like the rear deployment of the blades, but am concerned about the razor blade tip. It looks cheap and a potential to snap if you hit bone. Can anyone give me advice? Thanks, Fawndaddy
