Welcome to 3D Shoots!
To try to help you out a little I checked around here as far as Sales and popularity - sales would be 60% 2 Blade - 40% 3 Blade. As far as resistance on impact the larger cut with the 2 blade should be close to equal of the 3 blade with the smaller diameter cut.
As said when asked around here locally out of 400 = packs sold 60 % were the 2 blade and of all the sales the complaints were minimum. Note: read the directions - that’s the key to success some folks didn’t pay attention the o-ring placement in the back.
Hope this Helps – Good Luck Hunting this Year
