i've skied the 2008 dumonts and i really liked them..they were super light and poppy and fun. too bad they don't make them anymore. i had k2 disorderlys last year and they were polar opposite of that, so i'd count out anything k2.
this year i got the 2010 walls and i really like them. they're a little bit on the heavy side, but other than that they carve and spin really well. they're maybe a tiny bit stiffer than the dumonts, but buttering on them is really smooth and easy. for all mountain they carved well on ice (for the few days when the edges were still sharp) and aren't bad in like 6-8 inches of powder. obviously the tips dive under but they're still pretty nimble and fun. so anyway i'd definitely recommend walls. also im 6'3'' and 180 lbs just for reference, and ski 185s.
