I finally have given in to build a directional and am leaning to a quad fin setup.
What are you guys using as far as size of fins?
I am doing a 5ftx7in x 19in wide fish for allround chop and small lake waves.
The rocker I plan is basically flat to the front strap and then 4 to 5in at the nose.
Any comments on that I am all ears.

Cheers
Stan

I'm using probox PB450Q's on my board at the moment - but it's more a thruster shaped blank than a fish.

Worth having a look through their site the've got some great designs and the guys that run the biz are super helpfull. It's also one of the easiest plug installs going for home builders IMO.
