(Won't even enter a discussion about rotional weight, because then you realize that the supposed 20% weight difference is distributed over the length of the board and most of it has no influence whatsever in quick changes of direction).
* Water floats indeed: and any weight difference is cut at least in half because you are ... sailing on water ... not dragging your rig on mother earth.
* you say "comfort plays a huge role" in slalom but apparently this reverses in B&J and Wave? Do we have to conclude that Starboard "tests" demonstrate that a carbon construction is not as fast and less comfortable in a slalom board but actually is faster and more comfortable in a Wave board ....?
* By the way any discussion about carbon vs glass vs aramid is quite nonsensical. What matters in a sandwich construction is the core, and the fibers, and the # of layers, and the orientations used ( and the resin and and curing too). You can easily build a carbon board that is flexier then a glass board. Just discuss fibers is useless.
Some examples of constructions?
*** I ride Carbon Art boards that happen to be the most comfortable slalom boards I ever rode: I wonder how they manage to do that since they are 100% carbon.
*** AS far as I know, Mike's Lab builds everything in carbon but NOT the small sizes, where S-glass is the choice, for slalom too, because Carbon is simply an overkill in his opinion ...
