Don't know if you're familiar with the show: "Myth Busters" on Discovery, but last week they were shooting a crossbow into balistix wax and there was quite a difference between the penetration of the 3 blade and 2 blade broadheads they were shooting! The 3 blade only penetrated 4-6 inches, and the two blade was 8-10 inches!!!!!!! Same bow, poundage, distance, shooter, everything. I was impressed. Had never thought there would be any, much less that much, difference in penetration.

saw that as well...think about it though...it takes more effort for more blades to cut..slowing the arrow.....but unless your hunting BIG game bigger then deer,i think 3 or even 4 would work fine...dont forget 2 only slices at 2 spots...leaving probably less blood and less damage...but you put either through the boiler room and your game isnt going too far...

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.

Antime penetration is an issue, it's recomended to go with a 2 blade cut on contact type head. That just showed why.
