With all the talk about the rage BH's, I bought a pack and tried them out. My first observation is, I will not trust them to stay closed without a rubber band around the middle. I pushed the blades behind the rubber O-Ring designed to hold them shut. I had my doubts even before I shot that the blades would be held back. My bow is tuned very well and when I shot I could see some wobble and the arrow hit 3" high from 30 yards. The practice head flew perfect and hit the bulls eye. I tried again with the BH and same thing. So I got a rubber band from my hammerheads and put it around the middle of the blades. Shot again and no wobble and a perfect bullseye. I then put a piece of paper on my block 4X4 and shot another with the rubber band in place. Another perfect shot and about a 1 1/2" cut in the paper. The blades still opened on impact with the rubber band in place. The Rage does not come with rubber bands and wasn't designed to be used with them as far as I know. But there is a nice groove that holds the band in place, but it opens easily on impact.
My 2-blade "Rocky Mountain Snypers" (AKA Rage) came with rubber bands to hold the blades closed. My bet is that the rubber bands were prone to breakage and were replaced by the o-ring. It seems you may just be reverting to the old, albeit more reliable way of doing business.
