Killed several elk with rage 2 blades, complete pass throughs. I never use the same head twice though. One at 78 yards quatering still went through. I am sold, think about it, even a closed rage or mechanical is still only slightly smaller than some fixed blade like atoms for instance. This year I am going to try the wasp Z-forces, so far so good. Used to be avidly against mechanical, now I think there the only way to go on some game. If I was hunting say a buffalo, it would definatly be fixed just cause of the strength needed. I have guided over 75 succesful hunts on elk with a bow, and can tell you most if not all of the animals we lost was do to a poor shot placement not the broadhead. So in my theory I would rather shoot something that doesnt or needs very minimal tuning, and for me thats a mechanical head. Just my .02 Oh, i guess I forgot to metion it.. Yes, I did get the Red Carpet Treatment.. the farthest my elk have gone with a good shot with a rage was maybe 60 yrds... The one piled up at about 40yrds, and when he ran past me I literally got sprayed. Was devistating. I have also shot several with fixed, and have had blades brake off when the hit a rib, so would a mechanical. The last animal I shot with a fixed blade was a wasp bullet at 98 yrds. That elk went maybe 60-70yrds. They both work, I just like the bigger holes I guess, and the accuracy of a mechanical.
