Nowhere did I acknowledge that there is a difference in flex between the Proto and the SL. Now, virtually no two board models have an identical flex, but the SL and Proto are so close/identical that the difference, if there is one, is imperceptible to most people - and certainly to a beginner rider. There most certainly is no difference in the "kind of s[t]iffness" between the two boards. Incidentally, NS rates them the same for flex.
Also, although very slightly directional, the SL is still a twin. For riding switch the difference is again imperceptible to virtually everybody and certainly a beginner - if you cannot ride switch on an SL without issues, you cannot ride switch, period.
I'm looking to sell my 2011 NS SL 158 with Rome L 390 Boss bindings (2012)
I've rode it maybe 10 times, it's heavy and doesn't do much better than my Evo. I like my supermodel x and heritage more.
I think it's a great board for beginners though, damp and forgiving.
