Stock Fin For Carve 145

[Roly Gardner]

Hi All

Been catching up reading some of the other threads and have a quick question please. My Carve 145 has a stock 52 or even 56 cm fin which I use all the time since I only have the one! I also only sail with my 5.0m and 6.5m rigs at present. Can I get away with a smaller one or should I actually be using a smaller fin to balance the set up?

As you can tell from my terminology I am not sure what I am talking about so any guidance will be gratefully received.
