I'd go for a twin with more flex than an SL if I were you. Maybe a proto if you're looking for a neversummer. Thing is, you won't be riding enough pow or going fast enough while learning next season to require the kind of siffness and damp stability that an SL provides when you're riding 'all-mountain', and a twin will be better for you to practice riding switch while you're still learning. As soon as you get comfy hitting small kickers, it will be good to play around with buttering and little 180's...and the extra flex will make things easier and more fun.
Personally, I'm eyballing the proto or the flow shifty right now, and I think they'd be good for you also. Finally, you really can't go wrong with the Ride Machete. The only reason I'm not considering it is because I already have a board with a profile that's exactly the same as ride's low-rise rocker...and similar flex.
