Traditional - 5" fin. Though the 5" and 6" fins will fit in any of our shells, the 5" fin was the standard on our Traditional models, and the 6" fin is the default for our Advantage single racing shells. The 5" fin is less deep and less steep than the 6" fin. In weedy areas, the 5" Traditional fin sheds weeds a bit better. 

Fins are back ordered. They will ship by the end of August.
