no, too big is not a good thing



That's the case by definition... if a fin is defined as too big then it is by definition not a good thing.

Logic old sport.

Wow, breathtaking insight there Roy.

I'm with ob on this, those very pretty 10 inchers with the latest paisley pattern are the latest in hipster marketing - I have never really had much success with them though, they dont offer the performance to justify the $$ they are asking.

technically speaking bigger fins operate at lower pressure to produce the same amount of lift as a smaller fin and/or produce more lift. Slower speeds tend to favour bigger fins due to the fact that wetted surface area drag predominates at higher speeds, but there are other variables. If a smaller fin is being asked to produce more lift than it is able to it will lose efficiency via high induced drag and cause more drag than a bigger fin.
