We're all built differently and have different responses to the additional stresses imposed by fatter skis.
Interesting comment. Makes me think back to April when I spent a day on the Sultan 94. My knees really felt it at the end of the day, and it struck me as unusual, as I have never had knee pain on any ski, including 5 consecutive days in the Rockies on my Mythics (88mm). At the time I thought it was due to the longer length (184 vs. the 178 that I am used to), and the terrain (a lot of broken snow, bumps, crud), and just not being used to the new skis and knowing how to make 'em really hum. Perhaps all of the above....? I'll definitely pay attention next time I try a wider ski.
I wonder how much binding stand height influences the mechanics of stress on the knees. Seems to me, at first glance, that this would have significant influence. Lower stand ht. = more leverage needed = greater stress?
However, on the flip-side, my impression is that technology and production has reached a point where the major players are able to make really great skis with waist widths btw 75-85mm that absolutely rip on the frontside. And I mean rip in the lay them over, carve a series of deep trenches at speed kind of rip. The added bonus is, these skis do well in a host of other conditions as well-from over skied groomer crud, actually crud, corn, and light tree and bump use--all of which is part of a typical 'front-side' day of skiing (especially here in new england!). Look at the celebrated Movement Jams and new Head Peak 84s (neither of which I've skied...but I heard a pretty good carver liked these). Look at the new progressor series, or the kastle 78's, etc-it goes on and on.
I think the moving away from the 70mm waisted and lower high performance front side skis has happened because there are equally competent skis being made with more useful waist widths--this year's progressor line is a clear indication that positive trend. I don't think it is because people have lost the ability to ski and don't appreciate those sort of narrower skis anymore, I think it's because there are better options, even for the true expert.
Agreed on all points. Although I must say I really like the edge-to-edge quickness of a 70mm or narrower ski. There is just something incredibly fun and playful about a ski that you can flick over one edge to the other in the blink of an eye. Paired with a great pair of boots, you're in for a super ride! And to be honest, where I do most of my skiing (southern Ontario -- the
other Blue Mountain....are you listening, Mike?), there are so few days when I really need the float that a wider ski offers, and for that I have my 88mm Mythics. With the Progressor 9, I have a ski that works exceptionally well for at least 75% of my ski days, including soft spring mush (surprisingly). No need for anything wider, no need for rocker. But what I do need is exceptional ice grip, great high speed carving stability and smoothness, and a compliant shovel that can transition over crud and chop and not toss me. For me, the P-9 is it. Love it!
OTOH, if I were skiing a lot out west, like Gary for example, who seems to spend about a third of his season west of the Mississippi

, then I would likely own a 78mm ski as my narrow ski, and something in the 95mm+ range as a 2nd pair. For a skier like Gary, that kind of 2-ski quiver makes perfect sense.
I've heard a persistent lamentation that major ski companies aren't making enough true high-end, expert frontside skis anymore--and the lack of skis with waist widths under 78mm is often pointed to as the proof of this.
As a side note to that, it's good to see the companies taking women's narrow performance front side skis seriously. All of the major firms are making at least one pair of high performance skis aimed at females who want a
real ski underfoot. Fischer C-Line Zephyr (Ti laminate, flowflex race binding); Head Power One (basically a Supershape Speed with different graphics); Nordica Firefox (ditto -- a Doberman Spitfire with a different topsheet); Dynastar Exclusive Elite (a Contact Groove)....etc. When it comes time for my wife to replace her beloved Supershapes, there will be no shortage of choices , including all the great unisex skis.
Liam, like you said, these are fine times for ski gear nuts. Just so hard to resist the temptation to keep buying more....
