I have the 2011 wood Kode94. I am 82kg and 185cm tall. For me a 5.5m wave sail feels pretty much perfect on the Kode. I have tried it with a 6m no cambered freeride sail also but I didn't feel as comfortable on this setup. I can go down to a 4.7m and it still feels very nice. I also have the Futura111 which I use with a 7m sail.
