The SL still does plenty of things better than the proto. It certainly isn't the old proto. They certainly aren't interchangeable for the same riding style.
The only reason they aren't interchangeable is that the SL is more limited. With the new ProtoHD, your looking at even more advancements. I didn't mispeak, the Proto dominates. What's the point of an "almost" twin? I'm not going to sit here and try to own your mind or something but I'll stand by what I said and agree to disagree.
Just because you assert your opinions doesn't make them factual statements.
