OK Wouter, I will take a stab at it. Upwind the boat sailed more like an A than any other boat I have sailed. Not quite as responsive, but we were able to get the same feeling of the boat squirting forward in the gusts and not just healing more. The balance was not as good and we were back at the rear beam, which produced rear beam slapping on occasion (upwind). That really stopped the boat, but we wanted to keep the bows up in those conditions. One race sailed in light conditions, which meant we were either on the boat, single, trapped, or double trapped. The boat came to life just when I would expect it too, as opposed to a Hobie Tiger that feels very underpowered in single trap and below conditions.
Downwind we were pushing the boat more than we should have and went over twice. Most teams were sailing low and safe. After we went to this mode we did better. On the A I would have felt more like I was racing/ pushing the boat to get an advantage. This was fast, but not quite the same gut feeling as when you are in the groove downwind on an A. I think there would be a wind range where F16 is more fun, possibly between 5 and 10. After that and the A is challenge (read fun for me) to go as fast as the boat is capable, and before that and there is not enough power in the spinnaker to make it worth the extra hassle of rigging and crew work.
Summery: For a two up boat there in no question this would be my first choice, if there were a fleet of good racers in my area. For single. I think I would stick with the A. For versatility, again no question..the F16 wins.
