RE: Improve performance with new fin?
The MFC liquids are very nice freerace/freeride fins. They have very good potential, also in the lower wind range, but the manouvrability remains very well. These fins you have in the range 28 cm up to more than 50 cm. I have used them a lot in the past. A +- 40 cm may be very nice size: enough area for early planing and going on in windlulls and small enough not to get out of control soon. The speedpotential of these fins is really ok and jibing is easy!
