Once again many thanks for the response Roger.
Even from my limited experience I can also see that the guy I mentioned above sails underpowered. I will probably opt for the FU 122 with a 6,7-7 ish freerace sail.
One final question I have for you (...I promise that the next time you will here from me will be when I will actually ride my new equipment
), is what would you consider as a top-end wind range limit for the FU 122 at my weight? 20 - 22 knots maybe?
