With each batch of boards I've done, Jacky's board always turns out the fastest. The reason, width. The narrowest board wins, all other things being equal. Last season mine was 28 wide, hers was 27. Same rockers. This season mine is 26.5 wide, hers is 26.0 wide.
Here is the GPS data from the run showing when I was on Jacky's board. Fast and effortless glides that just don't stop.
