Maybe Marv can answer the specs and provide more pics:

i run it with 32cm Tectonics T43 with Zero Cant and it flies. The raceboard doesnt even come close to the top speed of the SL63.

The Slalom is also a lot easier, more gentle and forgiving to ride than the raceboards with their big canted fins.

I just love the feel riding this board. Its effortless and fast and still goes upwind pretty decent.

Weigh of my SL63 Proto Custom is 4.3kg naked.

... wow, they look great!!!!!
