I'm not nearly as good as I wish I was, not even close to epic lol, the kids in the park still put me to shame (I'm old, falling hurts more, and I heal a lot slower). In the mountains though, I'll usually ride anything that is not a "no fall zone".
The Raptor is going to be stiffer, when they say freecarve, it's going to be stiff enough to lay down trenches on groomers. That being said, at 200ish, you can probably handle the 159 easily, but the 164 is going to be more stable if you really want to fly. You can go with the regular width for sure. It's going to be a toss-up between the 159 for control in those tight situations vs. 164 for stability at speed.
If I was ~200 lbs, I'd probably get the SL in a 161. It's got the length to give you some stability, but has a bit more flex so can be forgiving when you're in the trees and need to toss it around. Plus, it is great riding switch. My second choice would be a Heritage 160 or Premier 161. These are a bit better all around than the raptor, slightly stiffer and more damp than the SL. The Premier is a bit more Freeride oriented than the Heritage. You're riding duck, so these make more sense. I used to be all about the stiff freeride boards (Salomon Fastback, Prior MFR) but now really enjoy the more freestyle oriented all mountain boards now. The SL is by far my favorite.
