75+ whitetails, a mulie, abear, a boar, and a few assorted smaller critters over the past 20 yeras with Muzzy. Never a failure.
I've heard a lot good about Rage but had occasion to help a freind tune his bow a week or so ago and was not impressed with them. He had plenty of trouble keeping them from deploying in the quiver. Other than that, they did OK.
The big problem with mechanicals, which have come a long way since the old punchcutter days, is that they wind up being a bandaid on a porrly tuned bow. A shortcut if you will.
Mechanicals are fine IMHO, but only when the bow is tuned properly and should not be resorted to simply because the fixed broadheads wont fly right.
