I've been shooting the buzzcut serrazors for the last couple years. I laid down a few deer with them. In my mind they are penetrator head and not bleeders. I stuck a dandy on a hard quartering to shot. Tucked it tight to the shoulder, exited through the guts. He only went 150 yards and piled up.The whole arrow was in the deer at one point, and was still stuck in the ground a foot after exit. Not much for blood though, but wouldn't expect much given the shot angle. Shot a few does with them as well, but never had one of those "holy piss" blood trails. All pass thru's and all the blades sharpened up great except for the one that hit a rock.
Aside from that, they fly very well. With my last 2 bows, they hit with the field points out to 60 yards. I typically run a heavy (500 gr +) arrow which helps with arrow flight
