Coming from someone who has worked part time in a archery pro shop, let me fill your ear up with a little info on the rage.
When they first came out I was shooting the rocky mnt snypers and decided to give them a try. The first set I bought didnt open on the deer I shot (in the pumper, broadside, @ 23 yds/ no reason why it shouldnt have). Two weeks later we got a letter from rage saying they were recalling all there broadheads because of this. I sent them back and they replaced them for free( they do have good customer service though). ANyways, with that pack they sent I shot at two deer and missed over both of thems back with some crazy arrow flight. A little time later rage recalled them again for opening in flight causing the arrow to plain(explains the crazy arrow flight). Needless to say after all this stuff, I am back to shooting my faithfull rocky mnt "Snypers". (Never had a problem with them, o-ring or not, they are the shiv) Good Luck though, hope this doesnt happen to you.
