How quickly do ski designs become obsolete?
Let me explain: I ski an average of 15 to 20 times a year; sometimes a bit more; sometimes a bit less. I tend to change my main pair of skis about once every 5 years, on average. I have never changed a pair of skis because they were worn out. I usually take good care of them.
Some of these equipment changes have been revelations; some have been disappointments. I must admit that I have sometimes fallen victim to ski manufacturer/ski magazine hype, only to find out the newfangled skis were not much different from my old ones. In fact, I can only remember three instances where a new pair of skis turned into an epiphany. The first such instance was when I purchased a pair of Dynastar Course Géant race skis in the late 80s. They were my first pair of "racing" skis. The second instance was getting my first "non-straight" skis in the late 90s (Volkl P30RC). The third revelation was in 2009, when I got my current Dynastar Legend Mythic Rider skis. I did not think that a ski that wide (88mm) could carve and hold an edge this well on a hard surface. I absolutely love those skis, and they have never disappointed me. I have used them in everything, except for bottomless powder. They still ski well and will last me a few more seasons. Which makes me wonder: is it time for something new? Are they old technology, by today's standards? For those unfamiliar with the Dynastar MR, they are 88mm wide, have a 21m turn radius, full camber, hybrid sandwich/cap construction. Back in 2009, they were pretty much at the top of the class. How would they fare today, against the best skis in that category?
BTW, I also own a pair of Blizzard Gunsmokes, that I have only taken out twice in marginal conditions (9 to 12 inches of new snow, turning to crud by 10 AM). The jury is still out on those, In both instances, I switched to the MRs before lunch, as I prefer busting though crud, as opposed to riding over it.
