Dude, where was this ski NOT popular? The Cochise nearly sold out early in the season (getting a 185 was almost impossible past january) and was probably the most consistently highly-rated ski of the season.
Powder week is sponsored in part by Salomon. I think the Cochise is a good ski, I would say that Blizzard also substantially upped their visibility in the market buy putting the ad dollars where it needed to be. I would say that the Cochise was well reviewed on TGR, but not hugely popular.
Again though, magazine reviews are about paying people to get on your ski's. There is a cost to show up to Powder week, and there is a cost to get testers on your ski's
Freeskier did somewhat of the same thing. There was actually appointments to have "reviewers" test your ski.
