IMO they are the best expandable out there. The two I bent blades on this year any head fixed or mechanical could have done the same. One hit a rock after passing through and the other hit the spine. I’ve shot 6 mature bulls since switching to mechanicals in 2019 and 2 broadheads needed blades, 1 dead meat chipped a tip off of one blade and 1 Trypan bent the blades. Both bulls I killed with Hyde’s the heads looked great.
I’ve killed a lot of animals with mechanicals and have shot several different brands and have never bent a ferrule. I have also ruined more fixed heads shooting animals than mechanicals and have shot them both for a similar amount of time. I’ve even chipped Iron Will S100’s bad enough they needed new blades and have bent a ferrule on a RMS Cutthroat 200gr with my recurve (I was able to straighten it).
My point is all heads can get damaged under some circumstances. I missed several antelope this fall with my Hyde’s and was able to just clean them up with my work sharp field sharpener and keep hunting. It could have been one of those that killed my buck and bull.
Here are a couple heads that each killed a big mature elk, not sure how much more you could ask for.
