RE: sharpening G5' s
I have one in the 125 grain version that I use for practice that has a couple of flat spots on two of the blades from banging them into other heads. Without removing a lot of the metal I won' t be able to bring this head back to it' s peak sharpness. I did run it over the stone the other day and it came out plenty sharp. It won' t shave paper as some have described above but I guarantee it would go through a whitetail like a hot knife through butter.
I wondered how it would fly so I took it out back. With a slight breeze I was able to hit a 3" spot at 60 yards three times in a row starting with the first time I pulled the bow back in the experiement. The fourth shot missed by two or three inches and the experiment was over.
