i have tried a bunch of broadheads. I like to shoot them through heavy plywood with a 2419 at 250-255 fps- that is 625 to 650 grains total. Just to see how they hold up. Here is what I have found. The muzzy 4 blades do better than the 3 blades- by a long shot. They are great heads.Our results on shoulder hits with game shows the same. The ferrul on the 3 blade bends more. The rocky mountains seldom hold their blades. The wasp hammer sst is by far the best 3 blade. I realize we dont hunt wood, but this is my test for toughness. To me, I would not shoot a muzzy 3 blade, but a lot of people do. Id shoot the 100 wasp hammer sst. But that is me.
