Those Prior boards are sexy! Pricey, though. Will have to demo next time I'm at Whistler.
I demoed the Prior AMF last year at Whistler.
Very solid, stable board. But there's nothing special about it versus mass produced boards from other companies.
Make sure you ask them to sharpen the edges before you go. I found the edge hold lacking.
I also demoed the LT Dark Series and Travis Rice Pro the same week.
I bought the Travis Rice. Very solid and stable but easier to maneuver than the AMF imo.
