I have a 2011 code 113 wood, and use it with a 7.2 and 6.0. Have used it in flat water and choppy conditions.
Haven't tried any smaller sail size on it though. But think a 5.2 will be OK. For smaller sizes I would have considered a less vol. board. My weight is 80 kg. The code 113 has a "loose" feeling and is very maneuverable. Nice and easy for fast small radius jiibes and fairly fast. Can recommend this board, bot not for sail sized below 5....
