So like most of us, I ascribe to the "straighter-sidecut-for-bumps" school, and I can/have explained why. But the other day, working through some Mini Cooper sized bumps on my carvers, thought about how most "moderate" sidecut race carvers destined for beer league courses have radii in the 15-17 range. OK, fine. Yet if we're talking about a midfat ski for bumps, that's waaay too deep. OK, fine. But exactly how can the same radius be very GS-like on a 70 mm ski and far too much on a 90m ski? Both skis will describe the same arc in the snow, although they will have different leverage at the waist. The wider ski will have more inertia at the tip and tail, obviously, since they'll be wider to produce the same radius. And will produce more force as they come around, since more force is required to get them started. But I don't hear about swingweight or inertia, I hear about hooking, about sudden pull-ins. Yet I thought hooking was a function of greater curves from the contact point to the tip, say, in softer snow. Yes, I know you can suddenly start to carve a bump when you don't want to. But again, how is that possible if the curve is the same? I know I'm missing something obvious. Is this more about disliking the sensation of a wider carver hooking up, even if a narrower one follows the same trajectory? Is it about the greater likelihood that a wider ski will make contact with the sides of the bumps while in the troughs? Explain, por favor.

All of my skis bend, I bend them through my inputs and where I point them.
When they bend, the turn radius of a clean edge changes (invariably reduces). and if that's not enough, I can slide 'em.
Any ski works the same, some are easier, but not different.
