I have been shooting Stingers for years now and they are absolutely GREAT heads. I bought the Snuffer SS heads last season and didn't like them as much.........not that they were bad........just not as good as the Stingers IMO.
I like the fact that I can shoot Stinger blades all summer and then just replace them the night before the season starts and go out with razor sharp heads that I have 100% confidence in.
I did have a Stinger break this year on the opposite side rib.......first non pass through but still good blood and dead deer. The 4 blade Stingers leave BIG holes and lots of blood to follow.
