well I have last years blends (07-08) in size 186 center mounted with px12 jibs. These are my only ski, I ski them almost entirely in the park and they have been amazing for my size(6'2 220lbs). As a park ski they are awesome, solid, 90 mil underfoot provides awesome stability. They have held up pretty good on rails/rocks/logs I still have no edge cracks or coreshots. As for trees I skiied them in 20" of WNY freshy at holiday valley almost entirely in the trees and they were great, awesome maneuverability. Onto the big mountain aspect... I used these for 5 days in snowbird and every day there was around a foot or so of new snow. Having them centermounted, this hindered performance in the powder greatly. I was always diving and summersaulted multiple times. But when I got some speed and leaned back a bit I could float relatively well with some slope.... might help, I'm bored.
