I'm all about the Pronghorn. It's different, it's silly rapid, ULTRA fast on the climbs and yet the fastest I've been on the downhills (admittedly not on singletrack due to the metre rule present instead of a handlebar) while also being the most fun – even I was jumping around.
However, for me I would always buy the 100mm Race with an adjustable fork on the front. It's even faster but the steeper angles will punish you if you're not good enough (which I'm not but it makes it all the more enjoyable) or you want a more relaxing, "all mountain" ride.
That said, the Zesty is a capable machine to say the least and they sell like hot cakes for a reason. Anyone who says they'll get their wang caught is either bigging themselves up or simply hasn't ridden one. Review of the carbon one here
