I shoot the rage 2 blade. Never had one open durring flight. and I can tell you why I use them. MASSIVE blood trails! Every deer I have made a killing shot on with them died quickly and the blood trail was so good that you could follow it at a fast walk and never loose it. I mean buckets of blood. I have shot thunderheads, muzzy, G5 monteks, and many others and never had blood like I get from the rages. You can almost stick your hand throughthe hole. Keep them sharp and keep the rubber o-ring new and no problems. I replace the o-ring every year.
