I used the Rocky Mt. Snyper this year and took 3 deer with it. One tried to jump the string (note I said tried <img src=icon_smile_wink.gif border=0 align=middle>) but I got her in the spine and she dropped right there. The buck I shot dropped about 40 yards away and the other doe about 70 yards away. The one thing I did notice was that the holes were not that big and the blood trails were not great. On the buck the blood trail was non existent so I was lucky to have seen him drop. The heads did their job, but I don't know if I will use them again.
