I do race FW and I am selling the AHD. I originally bought the Fu133 to replace the AHD but it never happened so I use the Fu 133 with mostly 6.0 & 6.6 sails. I was trying to go with a 2 board solution for sails from 4.5-8.2 with the Fu 93 & Fu 133. It worked but I lost a lot of planing power in the lighter winds.
You are probably correct in me needing to sell the Fu 133 and get the 111 or 121. In the end I’m just not going to cover such a large sail range adequately with only 2 boards.
