The carbonium top sheet definitely adds to the durability for sure. Not that any extra was needed, as all the NS line seems virtually indestructible. I like the SL but think it might be too stiff as I plan on spending more and more time in the park/jibbing. All 3 are close enough that I think there really isn't a wrong choice, and opinions will always vary. Good to hear specific thoughts though, really appreciate the input guys.
