Hey, I'm in Wyoming.
ALL our game is BIG! Moose, Buffalo, Elk, Bear, Mulies, Antelope.
10" penetration on a Moose is a far sight more attractive than 4-6".

I'm told our Antelope is as big or bigger than a lot of whitetails!
(lol)
I know, more cutting area on the 3 or even 4 blade. But more resistance to penetration. You know bow hunting, "close is good enough". I've used 3 blade, and mechanicals, now I'm going to give the 2 blade a try. They all work. Gives me something else to play with.
