Wanted to ask what you think about the size of a nubster rear fin on a fish style board. I did a hack job to an old board that I had sitting around for a long time. Converted a 6' stubby outline to a 5'6" fish. The board had sidebites added over the years, so I tried it with the existing fin plugs. I planned to add a set of FCS plugs to move the fins up and use large keels, so I cut out the C5 plug and made it all FCS. Havn't foiled the keels yet, so I just stuck other fins in there for now.
I still have have the old single fin box, so I can add a center fin if I want, but I think something really small might be the right choice. I hacked out a really small nubster thingy from a piece of left over G10 but I'm thinking it's too small to add much to the mix. Haven't ridden it since I added the FCS plugs and made the tiny fin.
Wondering what you think is the minimum size to have any affect?
