I'm not a big believer in the whole "one ski quiver" idea, but this may be as close as it gets. There are more specific skis out there for sure, but with this ski you can have a blast in any given condition. I have skied it in knee deep powder and chop, in both soft and hard crud, moguls, groomers, steeps, you name it this ski eats it for breakfast. It's the perfect ski for Jackson Hole, that's for sure. The cochise will make you more a better, more confident skier all around, even if you're already an expert. The only flaw I could find with this ski, Is that it doesn't excel in super deep snow, however it'll certainly get the job done. Other than float in deep powder over two feet, this ski kills it!
Size wise, I'm 6'3 185lbs, and I ski the 185. I could have definitely gotten away with the 193, but I ski a ton of bumps and trees, so the 185 made more sense. If this was going to be my only powder ski I'd absolutely and positively size up. Otherwise, it does not feel "too" short, even at my size.
Comparisons of similar skis Ive owned, to the Cochise :
Volkl Katana: Similar to the Cochise, but not as intuitive and forgiving. Better option for racing backgrounds, or more aggressive (pro level)freeskiers.
Moment Belafonte: More pop, but not as forgiving/intuitive. Better Edge grip and slightly more confidence on ice, but trades for worse powder performance. Better ski for traditional preferences.
On3p Vicik: Tip has more pop, more play, just as intuitive but not as forgiving. Exactly like the belafonte if it had tip taper, but made of bamboo, therefor more playful and snappy. Better choice for those with traditional preferences, yet still want something fun.
Personally for my mid-fats, I use the 185 Cochise for In bounds, and 184 Katana with for sidecountry.
