Tuning Hobie Turbo Fins

[dsafety]

Santa brought me a set of Turbo Fins for my Revo. Now maybe I will be able to keep up with the rest of the fleet.

These fins have an adjustment that controls the stiffness of the blades. According to the instructions, stiffer blades go faster but take more energy. More flexible blades are easier to peddle but do not provide as much thrust.

I am curious as to how other users tune their fins. Is there a noticeable difference between one end of the adjustment spectrum and the other? Is it important that both blades have the same tension? If so, how do you measure the tension to make each each blade has similar stiffness?
