I only have passing experience with the black canyon, but we did chrono the bows next to each other. My 58@28 pronghorn vs a 60@28 black canyon. The canyon was faster every time with 3 different shooters by about 10 fps.
My Pronghorn did average 170 with a 560 grn arrow. Black Canyon did average 179. Really fast bow. In the time I spent with the Canyon, I noticed these things:
The Canyon was louder, but not by a lot. Still a quiet bow.
The pronghorn was more forgiving and had a smoother draw. I honestly feel like the pronghorns are one of the few bows that truly feel way lighter than they scale, by a lot.
Fit and finish is beautiful on both.
Mike hays bows feel like they got a lot more tension at brace.
That being said, my Pronger is my favorite bow, I shoot it better than anything else I've owned. But I am ordering a a black Canyon come Christmas
