Tried this today and was really impressed.. I normally like my board loose but two trimmed down 2.9's was too loose... I installed a new 2.9 fin on my toe side and the small 1.9 fin heel side and wow.. what a difference.. Tight control and super fast spins..
Makes sense.. Catamaran racers (NACRA) have done this for years and also suspensions on circle track cars..
Has anyone every tried this setup?
