Rage 3 blade...none

Muzzy MX4? For a head that is touted as one of the new inherently accurate short ferrule designs I wasn't impressed.
Those things gave me fits. Even out of a perfectly tuned bow unless I choked the crap out of them with at least 4" feathers and a hard helical they seemed to have a mind of their own. I thought I was losing my mind trying to group tune them but I've heard this consensus from too many people who know what they are doing to dismiss it.

I sat out back one night with about 8 different broadheads messing around testing flight etc and could whack any of the 7 together but when I would get to the MX4's it was spotty at best. I'd have 2 that would fly sort of in the middle, others left, right up down...and worse yet they never seemed to do the same thing twice.

They drove me nuts and I never did use them obviously.

Oddly enough the MX3's flew great...........go figure.
