+1 for 4evrhtn, i tried the 2 blade one season for antelope and whitetail, the antelope was a big buck that was shot a 20 yrds broadside with a mathews switchback xt 60lbs 29 1/2'' draw and a goldtip xt hunter, went clean through without touching a rib, he died 50 yards later. Complete opposite with whitetails, shot a doe in the early season at 15 yards, hit a rib and it barely went in 3 inches, she ran around me and i seen the shaft had hit her perfectly about 2" behind the shoulder but barely penetrated. Never found any blood or the deer, went back to muzzy 100 3-blade and had complete pass through's the rest of the season on 3 deer.
