How bothered are you about weight?
I run nics on my XC bike because they're nice and light, fast rolling, they seem to work well in "most" conditions, i do find them a bit twitchy although thats more because i only run 2.1s on the XC bike.
My other bike has a 2.35 62A UST high roller on it, i actually prefer the way it feels probably because of the slightly higher volume. But other than that grip levels very similar just slightly more stable (due to the extra width)still quite fast rolling esp with a Larsen TT on the rear.
Given the price difference isn't that much any more (www.nextdaytyres.com) i'd be inclined to use high rollers for what you want.
and, FYI i've never actually had any issues with the sidewalls on any schwalbe tyres or single ply high rollers, even crunching through the frost at the moment.
