it's already been said, but either volkl bridges, or mantras will suite what you're looking for. the mantra is a bit stiffer, but the bridge has a bit more sidecut to it.
Seems like Kingswood used to make a ski that was about what you needed, I think it was called the midfat, came in 185 and was about 100 underfoot, and if you could get a pair of those in the extra (or whatever they call the stiffest flex they have) that might be what you need.
I dont really think you are going to notice the difference between a 95 waist and a 100 waist all that much. 5 mm really is nothing. Something in the dynastar legend series might do you well... the xxl might be a little wider than what your looking for but I think they have on that has a smaller waist? I demoed the the XXL at Alta last year and it was nuts. it was like a 193 and i wanna say 103 in the waist... could be wrong about that... but in any event it was crazy stiff. A solid powerful ski.. I was a little too burly for me seeing as im only 150 pounds... but at 175 you might be able to take more advantage of its power. But it deff sounds like your looking for something in the legend series.
Well I'm just throwing out some of the longer, stiffer twins that I know of, seeing as how you don't want to go over 95 at the waist, you cut alot of skis out. And in general twins are soft skis, there are far more non-twins out there for all around ripping that would be more suited to your needs.
