RE: Stinger broadheads
I like the Stingers a lot. I used a 150 grain last year with my Longbow and took a very nice buck. You can resharpen the heads easily with the right tools. The blood trail was exceptional. I will either use these heads this year of the new Muzzy 200 grain Phantoms.
On a side note, there used to be a picture on the Magnus sight (may still be there) of a shot that penetrated a moose shoulder blade. That was with a regular carbon steel magnus but it was still a cut on contact.
