I've not had great luck getting Snuffers sharp. I really like the design and they shoot great, but I've never hunted with them because of the sharpening problem. I read an article where a guy was using a propane torch to draw the hardness on them down and he said it made them easier to sharpen, but I haven't gone quite that far over the edge yet.
Wensel Woodsmen heads, a longer version of the Snuffers, are supposed to be easier to get sharp, but I haven't tried them.
I've shot Stingers and they shoot great also. But so far I've stuck with Magnus I and II, Zwickey Eskimo, and Bear Razorheads for hunting.
I've also hunted with Muzzy 125's from my stickbows and they do well. I do a little honing on the trocar tips to make them genuine cut on contact heads. Little know fact for trivia fans, Jon Musacchia - the guy who invented Muzzy broadheads - was a traditional shooter.
