Had the pleasure to sail an F20c a couple times when I was Singapore over the winter, and even though it was light every time, the boat was truly awesome. If you have the means, and you want to distance race, there is no question!
If your running distance races, there is no substitute for water line length and sail area. With a money-no-object perspective bling on the beach baby.
If you are doing cans then even if you have the means, it is just cause you want it, the bang factor does not seem to be there. I ve seen some results (spring fever being 1 I can remember) where there were F16's beating the 20c boat for boat in races.
Over compensation can have its risks
