The CLS9 is the answer to your all mountain needs. A really solid mid flex boot, but with all the frills of a high end boot. Sometimes it bums me out that all the high end boots with all the cool features are always the stiffest boots in the line. The ozone liner keeps my feet warm but not sweaty with its air circulation. Also the Skull Candy collabos are awesome. Plus you get a free pair of head phones. I like these boots a lot!
