If you want to make quick turns edge to edge, maneuvering in the bumps, there's nothing better. They smear very easily at low edge angles, but grip well at higher edge angles. The edges of small turning radius skis can catch in uneven terrain, so that it's hard to release for a rapid edge change. Mogul skis are good for icy bumps and for a narrow stance. If any of those benefits don't help your style or objectives in the bumps, then other types of skis are probably better. I see lots of people with the twister. I see a few in that last video I posted.The past several years I've decided to quit avoiding moguls or slowly gaping through. With tips here and elsewhere, watching others and... skiing moguls, I've gotten a lot better and can actually ski them. Especially smaller, softer bumps.
I usually practice moguls on "groomer days". That means I am on FIS SL tuned .05/3 or Head Monster 83s tuned .07/3, sharp tip to tail.
I'm wondering if I would find it worthwhile to add a real mogul ski to my quiver (even if it means swapping for a few laps in the bumps on those days), and if so, what would those if you "in the know" recommend? If not, should I have a pair of narrower all mt. skis with a more forgiving tune for mogul time?
