I have used the 125gr Rage 2 blade in Africa in 2016, with a Hoyt Carbon Spyder at 70lb with a 30" draw length. the 750 gr arrows were choreographing at about 263fps and getting good penetration on 12" of ballistic gelatine with a Plywood "ribcage inserted into the mould. They also shot and grouped well as one would expect from mechanicals.
In Africa....
* A Nyala bull at 24 yards.... Complete pass-through and 10yards beyond, animal drops within 35 yards.
*A blue wildebeest bull at 37 yards, complete pass-through and 26 yards beyond, animal drops within 45 yards.
* 3 large male warthogs at at 15-18 yards. 2 perfectly placed shots passed through and hit an embankment, they both dropped within 30 yards. the 3rd animal seemed a great shot with a pass through, but I only took one lung cleanly and it ran 600 yards.
* A Waterbuck at 35 yards gave a pass through that saw 3" of broadhead poking through the bone of the awkwardly placed opposite shoulder of the animal, it bled out at 35 yards.
On each of these animals I was present at the skinning shed to see results of my shots. I noted no defects in broadhead deployment, with clean, even massive wound channels throughout, where bone was encountered it was a surprisingly robust hit. seeing the results inside the animals, it was apparent that they were doing the job they were designed for.
Regarding potential problems with Rage broad heads.... in my opinion it may be all too easy to assume a clean hit when it is anything but that, and any long blood trails in my experience were more on account of my accuracy and often awkward animal movements.
I will say that care, attention and checking must be given to these broad heads, before, during, and after hunts, and also further that I have only ever rarely re-used them after a shot, preferring to have everything, perfectly aligned.
I have noticed that after a pass-through shot, the hard African ground that is familiar to us is very unforgiving to the alignment of the blades when it stops the arrow.
My 10 pence worth and no I don't get sponsored by Rage and I use a wide range of broad heads as required.
