Hi Remi, again
Another friend who own a 122 2010 Futura wants to get better performance of his board with 2 new fins.
He wants better speed and upwind riding for two sails: 7.5 and 6.5 Elements. He´s medium weight and medium level of windsurfing.
Which sizes of slalom fins will be better for him


Thanks a lot
