2 years ago I bought a SUNNY (Mod.2006), to use in duo with my wife (and few luggage). I have been so happy with it that, this year, I bought a second one (mod.2008) to use them in single. So we can go for a few days instead of daily sail. One important thing : to really take advantage of the sunny boat I recommend the use of the fin. It is sold as an option, and with the fin the boat is really an other one. With mod.2008 (and following ones I suppose) the fin support is pre-installed. And there are several improvements between 2006 and 2008, mainly concerning the seats and the way they are mounted in the boat.
SUNNY is really a nice KAYAK.
