After a poor snow season, I've been getting annoyed at how quickly Burton stuff breaks! My second custom X lasted about 15 days before it had countless core shots and three edge breaks. Admittedly, I was hitting some rocks and riding hard at Kicking Horse, BC, but I can't afford to buy a new board every month - I'm in my third straight winter and plan to go straight to New Zealand and then back to Canada. I'm a level 2 instructor so ride quite aggressively and needed an all mountain freestyle board to support this and last for a good length of time. The SL is stiffer than my custom X and carves all the better for it, great all over the mountain: trees, steeps, airs, park and backcountry kickers. It feels tougher while still be relatively lightweight and has a nice flex for butters and ollies and aggressive rebound for advanced riding. My only concern is that the maximum stance width is a few inches too narrow - I'm used to Ride and Burton boards with super wide solid stances (I'm 6ft 3).
