I like the look of NAP Bloodrunners. I don't have any experience with them, but I hear a lot of good things about them and they still cut if deployment fails. I shoot NAP HellRazors, but they're fixed blade. With 55 pound pull, I would definitely go with a head that still cuts even if the blades fail to deploy. Personally , I hate mechanicals. I've never had a good experience with them, especially the Rage. This being said, I will also tell you that if you do end up getting mechanicals, don't try to find a hard core bargain because a cheap mechanical will be the worst head you will ever buy. It's this way with virtually all broadheads, but especially for mechanicals. Good luck!!
