Glad to hear you are getting your skills polished up to be able to sail the smaller boards comfortably.
Yes, the Kode would be the Starboard equvalent of the Freewave and freestyle wave.
From your last comments, it would seem to me that you still need to work on your "tuning".
Could be that some of your issues with the faster boards with harder rails and flatter bottoms could
actually be tuning issues rather than problems with the boards in your conditions.
Get some more experience on different boards, and learn to tune them to be fast and loose, and you may simply fly over some of the chop you are finding, giving you both better speed and that "buttery"
smooth feeling over the chop.
It's not something I can simply explain, but if you move things around, change mast foot positions,
footstrap positions, and rig your sails a little differently, you will begin to learn what works, when tuning,
and what doesn't work.
Hope this helps, and thanks for sharing your progress with us.
