smaller fin for s-type 115

[surfsjef]

Hello,

I have a S-type 115. Great board. It includes the standard fin. I use a North Sails Daytona 7.3 m2 and it just runs perfect!

With more wind I use a Daytona 6 m2. I think I should use a smaller fin than.

What smaller fin and which size do you advise?

Thanks in advance!
