Any body been shooting these? How do they perform and are they easy to sharpen super sharp?

They are decent heads, I actually think the double bevel is the best of the three.  The single bevels need to be harder steel to maximize the benefit of the single bevel IMO, and the factory grind is not very impressive on the single bevels either, although they sharpen easily with a file.

They fly fantastic and are plenty strong.

Although I have not yet used them, I have friends that have...They work great! Plus their reputation speaks for themselves! There is a reason they have been around for so long. I will be trying them also this fall!

What Slowbow said.  I didn't like the single bevels I had in the No Mercy.

shot 2 small WT bucks with them last fall with the single bevel and they performed very well, but I would agree that the steel is a bit on the soft side and the ones I was able to find were only 135 gr. so I had to add some weight to them to get them where I wanted them.
still waiting for the Grizzly to come out with a left wing bevel.
