I love these broadheads. Lots of damage and great cutting. I use the 3 blade 100 grain spitfires. I started with the 2 bladers originally. The first buck I shot with the 2 blade spit fire went right between the ribs and the deer never felt it. He just kept right on eating. He walked 40 more yards and fell right over on his back. LAst year, I busted a button buck(thought it was a doe) through the shoulder, heart and lung.. I broke his shoulder blade.. Broadhead went right through. These bad boys are mean. I will never use anything else.. atleast on a whitetail anyway.. I dont think I would want to shoot a moose with one..
