Wish I could. I have not ridden an SL yet. Sabatoa owns a Legacy (wide version) so I'm sure he can help you with some info!
Not until I ride the Cobra.
I think my personal riding style is actually drifting the opposite direction the Cobra towards a Proto type board, something true-twin rather than directional. I'm hitting more features, more kickers, trying more freestyle, etc.
For now the Legacy is exactly where I should be but the next board will be a true twin.
