i have used, and highly recommend, rage (2 blade) for 4 seasons now and i wont change... I put a friend on a buck on thanksgiving day and he was shooting the 3 blade rage.. shot was a little too far back and low, and the blades didnt open up properly, and we ended up not recovering the animal after giving him plenty of time and several hours of tracking. Had they deployed we possibly would have found him in short order. but that is why i dont shoot the 3 blade just in fear that more moving parts means more chance for failure. BUT i have never had a 2 blade fail me yet and ive shot 10 deer in 4 years with them- none have gone more than 100 yards, even on a questionable shot.
