Muzzy also now owns the Phantom heads. I have a few of them around and they are similar to the stingers. The only thing that I don't care for with them is that they are a bit noisy. I'm waiting for the new stingers to come out with the150 grain head (they were suppose to be out already). I have some back ordered from Cabelas. To get the two bladed heads sharp, I use an s-24 sharpener and leather strop (got it from 3 rivers). I put the sharpener in a vise and leave the head on an old arrow when sharpening. Use plentyof oil.

A little trick that Arthur taught me on the regular Muzzy's is to take the blades out (leave the head on the arrow) and sharpen the trocar tip on a flat stone. It will take a while to get them real sharp because of the hardness of the tip, but it can be done. That will in essense make it into a semi cut on contact head.
