Not an S7, but I've been on a number of 110+ demos, but only on powder days and super soft bumps. They were fun in pow bumps, but I'm pretty sure would all be a handful in firm bumps.
So, I did buy a 110 Sickle. For the fun of it, I'm going see how far I can push them to work in bumps (I know it's not the same shape as the S7, and that's by choice for other conditions). I'm not hopeful for the Sickle in firm bumps, though, as I've yet to see anyone rip a zipper line on a 110. I'm thinking of shooting video skiing the exact same zipper line on my 80, 90, 110 quiver. I think it would be pretty clear how much more difficult bumps become on wide skis. Length, flex and sidecut matter too, of course.
Not the same ski at all. I've never tried a sickle, but the rocker with a conventional sidecut really makes it sound like it would have the same problems I ran into with Obsetheds. Completely lacking in the specific qualities that seem to make the S7 & ilk (I've tried several 5 points in the bumps and liked all) such surprisingly fun mogul skis.
The next demo day you find yourself around, do yourself a favor and take some 5 points out for a bump run. I think you may be surprised.
