Heck, I love Rage heads. I have literally shot dozens of deer with the 2" 2 blade version and have never had a head fail. On well placed shots, they will leave a blood trail that looks like you hit the animal with an axe. On poor shots, you will often do more damage than with many other heads. The only place I would rate them a little behind a thunderhead or muzzy would be on the shoulder. Fixed heads are tough to beat on a shoulder shot. But that being said, I have still recovered every single deer I have shot in the shoulder with a Rage and several of those have blown through the deer and literally dropped the deer in 30 yards or less. On some shoulder shots, penetration has been an issue, but the internal damage is usually tremendous.
No head is perfect and they all have their pros and cons, but until I find something that I like better, I am shooting Rage 2 blades.
