In all seriousness, the Proto to me is a slightly stiffer park deck, but it's still a park deck. It'll handle the whole mountain fine, but not great, IMO. If the trail is smooth and groomed it'll fly. If it's pushed around freshies, then it's a bit of a chore.
Ollies were pretty good though. I'm really close to pulling the trigger on a K2 Happy Hour though, to see if the pop is much better. Really getting into popping off hits and what not, so I'm trying to find the poppiest all-mtn board out there. The lifted profile, ollie bar etc. sound great.
