I switched from 2 blade 100gr rage to the new Hypodermic 2 blade. Mainly for the better blade containment on the Hypodermics. The original rages had a tendency to pop open if they got bumped on brush or pushed a little to far into the quiver. The containment bushing on the Hypodermics is a much better design. This last weekend I killed my best mule deer to date with them. The shot was 92yds broadside. I shoot past 100 almost everyday and felt very comfortable with the shot. He was broadside and not spooked. The arrow passed through and was hanging by the fletchings out of his right side when he turned and ran. It dropped out within 10yds. He bled a ton for 50yds then dropped dead. The entrance hole was unreal. I could almost fit my hand in it. The exit was almost as big. I clipped a rib off on the way in. The deer was almost as big as a cow elk body wise. I am shooting a carbon spyder 34 76#'s @30" draw. I didn't have any heads pop open while stalking through the brush. Just my observations but I am sold on the Hypodermics.
