Advantage - 6" fin. Though the 5" and 6" fins will fit in any of our shells, this is our default choice for Advantage single racing shells. It is deeper and has a steeper angle than the 5" fin that was the standard on our Traditional models. In weedy areas, the 5" Traditional fin sheds weeds a bit better. 

We also have 2 specialized options, a "Chula Vista" weed shedding fin, and a 4.2" smaller fin for head races (same price as regular 5 and 6 inch fins).
