Like Smokin 250 said, they work when they work. When they DON'T work, which happens regularly, bad things happen. Use the head you want to, I don't care. But, it's a matter of time until the Rage crap will fail and you'll change your mind. For me, it was on one of the larger bucks I've ever shot. Had I used something other than over-hyped junk that day, an easy recovery would have happened.
