Did you try ROCKY MOUNTAIN SPORTS if I recall it is on roswell road. When I lived in ATL that is where I went for most of my stuff. Other then that I think there is a shop in Norcross that carries NS longboards might be able to check with them and see if they can track one down for you.. Can not remember the name of the place in Norcross butwould really check Rocky Mountain Sports.
I did call Rocky Mountain, and they only have 1 2010 NS board, but wasn't a SL. Think it was an Evo. I think the Norcross store you're referring to is Woody's. No luck there either. I might end up buying from boardroomshop, as it seems like that's the only place where I can buy it new.
Yeah it seems like NS sells out on their boards extremely quick. This'll be my first NS board, and I keep hearing nothing but good things about it, so I can't wait to get my hands on one for this season. Thanks for the heads up though :]
