The yellow is the original style. The blue didn't come along 'til much, much later. I started this thread because two people mentioned to me on the beach that they wish the board was still yellow to get that old TTMB feel. I had it on blue for one day when the default when to blue, and it lost that 2coolfishing feel to me, so I had to switch it back to yellow. I figured there were probably others who didn't know they could change the look back to the old TTMB/2coolfishing look.
