I'm about a 90 percent two blade man but I'd hunt with a snuffer anytime and have.
Two years ago a buddy shoved a 160 grain snuffer behind the shoulder of a 182lb buck, angled back that came out the side of the paunch and dropped out.
He was sick with the shot (he said the deer turned right when he shot) and the mess but it definately worked. The buck made it about 80 yards straight down the creek before piling up.
I think it was about his 10th Snufferized buck.
Oh yeah.........he was shooting, and always has, a 45lb Super K drawn 27 inches with a 525 grain total arrow weight.
He DOES take pains like most of us to have perfect arrow flight, which is important regardless of the head type.
I like other heads better but there is certainly nothing wrong with and probably not much big game that hasn't been Snufferized successfully.
Good luck!
