If I had the money to get another all-mountain board, it'd be the Coda. I own a NS SL and I love it to death, but damn those Arbor woodgrain finishes are sexy.
As for how the SL handles, it's very agile and quick edge to edge. It also holds carves very well thanks to the vario grip and camber portions of the board; I can lean deep into them and come out without a hint of skidding. The rocker between the bindings let's you float along powder with ease, but it does give it a pivoty feel if you're flat-basing while bombing a groomer. Just leaning forward a tad though negates that problem, however it is something some boarders may have reservations about.
