i was extremely anti-mechanical until they came out with the Rage. What i liked was the concept of the rear deploy blades as opposed to folding open from the front, like they all used to be. also, they are mechanical, i like to keep hunting set ups as simple as possible. i have shot NAP nitros, thunderheads, and G5 montecs, and muzzy 3 blades, all excellent heads.
then last year I shot the rage and will likely never go back. i did not get a pass through on the first deer i shot because i hit the inside of the far shoulder. i had a blood trail that a blind man could follow, from the entrance hole. i never had a blood trail of any kind from an entrance wound before. when i recovered the deer, in site of my stand, i could fit my fist inside the entrance hole. now, it was opened up a little from the deer running, but that broad head left a massive hole all on its own. i shoot the two blades, by the way.
im not a huge fan of the o-rings you need with the rage, but you can buy spares, which is nice because i usually break mine when i shoot, and they are really dependable. i dont worry about them opening in flight. the blades have a little notch that hook underneith the o-rings, unlike other mechanicals that use a rubber band wrapped around the outside of the entire set of blades to hold them closed. they also fly exactly like my practice tips, which is the biggest bonus for me. if i could tune my bow so perfectly that my fixed blades would fly just like my practice tips, i would stay with fixed blades for easy and simplicity. but myself and both my brothers use Rage and we love them, they really are great broad heads. i actually am yet to talk to anyone personally who has tried the rage and not loved them. its a mechanical, so there is always that slight chance something might fail, but i have shot them enough to feel confident in their performance.
