Just throwing out what info I would like to see when looking at board specs.

Width
Length
Tip width: (not really all that important)
ROCKER!!! <<<< Super important info that is needed. No not more rocker than X board either but an actual measurement.
Rider Weight Range: for the board size. How is it the wake industry can come up with these numbers and the kite industry not?
Flex Rating or Stiffness: something like 1=Wet noodle 10=Steel Girder. (would be even better if it was an industry wide standard, but that is asking for way to much).

straps and pads
