no experience on any of these, but i thought the Lyman did indeed have channels on the sides than ran through the center of the board.
i know the 2012 version did. the changes for 2013 i think were pretty minimal. the 2013 lyman pics are difficult to make out for the bottom features because of the black base and the video seems to focus more on the tip and tail too.
the lyman has additional holes to adjust the fin placement which might be nice for the air tricks?
