If you plan to consider the Mantras, be sure to demo a pair in different sizes before buying. I bought the Red Mantras in a 184 as everyone said that was the proper size for me (6', athletic, 195-210lbs, 70-100 days per yr on snow, east and west). Then I demoed and bought a pair of the White Mantras (sounds like a Karate Flick!) in a 177. The White Mantras are stiffer than the earlier Red version. I'm selling my Red 184's and may even give them away to a buddy as they now gather dust in a corner. Maybe I'll make them into a chair or something

Sounds short but they Rock. If you shorten the length on the Mantras you get much more versatility w/o sacrificing speed and much float. My buddies noticed a big difference in my skiing, east on ice, moguls and hardpack, and especially tight woods at Stowe and Burke, and west in boot to waist deep pow chutes and bowls, etc....
I went back to the Red 184's for a month just to "check myself", including a trip out west in pow, and totally missed my 177's to the point where during the last couple of days of the trip I rented a set of White 177's and left the Red 184's in the condo for a return to Nirvana.
