Been skiing up at Sun Peaks a bunch this season, I think you're Volkl 6 Stars will do just fine out here, my ski of choice on this mountain are the Atomic R11s, seem to be similar under foot. The snow is rarely real deap, I find myself grabbing my R11s much more often then my K2 AK Launchers.
I spend very little time on the groomers here. Check out the east facing areas off of Top of the World, as well as the various marked gladed areas. Once you're board with that head out to the Gils (might need to talk a local into showing you out there although the traverse is pretty easy and gets well laid in and the out run is also marked from many areas). I'm going to be in Tahoe the first week of March but back after that, if you're gonna be around then drop me a note.
