I'm not sure a review will do this ski any justice. The Cochise does it all. I'm on my third season with the Cochise and it just keeps getting better. You don't hear about Blizzard as much as other brands (Rossi, Volkl, Armada, etc.), but don't let that scare you away from this ski. I've been skiing Blizzard for over 12 seasons now and have yet to be disappointed.
I'm 5'11", 170 lbs and ski the 185. I spend my time at Utah resorts. As mentioned above, the versatility of this ski is amazing. It's unbelievably stable at speed on hard pack (think 70+ mph on a groomer), is playful and responsive in tight space, floats plenty in powder, and excels in crud and variable snow. I've recommended the Cochise to a handful of friends and all now have the same affinity for the ski.
If you're looking at buying this ski, you're probably doing some homework and comparing different options. While I don't have a ton of data points for you, this one might be helpful. I skied a few runs on the new Rossignol Soul 7 recently, another very popular ski this year, and came away thinking the following: the Soul 7 is definitely a lighter ski and just a bit more responsive/playful than the Cochise. Was a really fun ski to ski. That said, it wasn't as stable as the Cochise and doesn't power through crud and variable conditions the way the Cochise does. Granted, my experience was only a run or two so take the opinion with a grain of salt, but might be helpful nonetheless.
Bottom line: I've been skiing for a long time and this is my favorite ski I've ever skied on. If you're looking for a one-trick pow pony, this isn't your ski. Likewise if you're looking for a true carving ski. However, if you want something that does it all, and does it all very well, this is the ski.
