I still have my old (school skis 202cm GS and 207cm slalom)[, but hafve rented a lot of demo parabolic skis. There are good and bad things about both of them. I consider them like the Original (bighead) Prince tennis racket or the huge perimeter weighted golf clubs. They make it easier to turn with a lot less hip angulation, so it is easier for beginners and infrequent skiers to carve nice turns. The shorter ski and deeper sidecut also make it easier for the pros to go straighter from gate to gate and make quick turns. This design is just an extension of the origianl deep sidecut skis like the first K2 Extremes with the 8.3mmm sidecut (later followed by huge 10mmm sidecut skis). Now that is a tiny sidecut.
I do think that your typical all-mountian parabolic ski chatters much more easily than the old school skis. It isn't noticeable at normal skiing, but try hitting 35mph on th frozen ruts and you will notice roght away.
The skis that the World Cup GS, Super-G and Downhill guys use are not your typical parabolic skis. Even the old school skis were slighlty different. A few years back (maybe 1995) I demo'd some World Cup Downhill skiis (223cm) for a speed skiing event. They were phenomenally stable. I could bomb through an entire run of small moguls with only a couple long sweeping turns with no ill effects. Incredibly stable! I made it to 85mph in the event.
Width does not necessarily mean stability. That huge sidecut that allows quicker faster turns with less angulation also means that it is easier for the ski to catch an edge and "wander"
I don't know the Outer Limits, but your average parabolic ski will chatter faster than your average old school ski at speed. Comparing race stock with that is like comparing an F1 Ferrari with a stock Corvette. I have personally skiid my old school GS skis and the run the same runs and courses on demo parabolics and noticed a difference on the bad stuff.
They are great under most conditions, but I like a less aggressive slighlty narrower ski for the really fast stuff.
Crashq â€“ Most of us commenting are doing so from recreational skiersâ€™ perspective. Those who race do use skis specific to that application. From my observations of the Okema Racing Team is that they prefer Voklâ€™s racing skis. The side cut, lengths, and tuning are very different than the recreational boards. But the overall shape is more parabolic than it was a decade or two ago and the lengths are shorter.
BTW, you 202 cm GS and 207 cm slalom skis would have been considered short in my day. I skied 205 cm in the bumps and 215 cm for slalom and GS.
Getting back into skiing after a 15 year hiatus has been a real eye opener. The clothing is less bulky and yet very warm. The skis are easier to control, the boots are much more comfortable, the bindings are integrated with the skis, and most everyone uses helmets. And even though the knees are not what they used to be, skiing is like riding a bike â€“ I was very comfortable after just a Â½ run from the summit.
