I shot the 100 grain wac'em 3 blades for a few years but switched to the shuttle t lok mainly just to try them and have killed many animals with both. The bull I killed the last year I was shooting wac'em broadheads and the bull I killed the first year shooting shuttle t lok's were nearly identical shots as far as the same bow, arrows, draw weight, shot placement, and yardage and I can say that the shuttle t's are far more effective. I will dig around and take a couple pictures of the broadheads but both of them remained intact but both went through bone and the wac'em blades just did not hold up well. The shuttle t on the other hand I could of picked up and shot again, you couldn't even tell the broadhead had been shot. Neither bull went more than 30 yards and expired in mere seconds but the wound channel from the shuttle t's was far superior, nearly twice as big, and along with that the blood trail from the shuttle t's had probably 4 times the blood! Hope this helps.
