The Pivot certainly does cope with being hammered downhill. I’m not in any way blessed with the vision to pick out nice, smooth lines, and so the Mach 5.7 I tried was a revelation battering down Dumyat. 150mm Rockshox on it. It was tough find anything it felt dodgier on than my 36 Float-equipped Pronghorn, and that was a random demo bike setup vs how plush my own bike is set.
Pivot is DW link as well. Certainly climbs a hell of a lot better than the Zesty I tried. I think the “too XC, is it man enough?” worry about them is down to how nicely they pedal.
When the Pronghorn eventually dies, it’ll be a carbon Mach 5.7 that my kit gets transferred onto.
