Need some fin placement advice.

Going to set up a board with a set of futures ft1 twins plus trailer, plus a set of the original c5 boxes/fins. I’m thinking it’ll be a twinzer-type setup, with the option of the small trailer. The board is a balsa compsand, way over-engineered, about 22" wide, widepoint forward, arctail. I stole the outline from my bumblebee bonzer, seen here:

I’ve never done a fin setup like this, and I’d really rather not screw it up too much. It is good that the c5 boxes are adjustable, so I can tune there, but the main fins will be set in stone. I’m heavy on the front foot, so should I put them a little forward of where I would put a thruster set? Or right at the same place? What about toe? I know, these are always the same questions, but I couldn’t find this particular situation referenced in the archives, so I figured I better look for help this way.

Thanks!

oh come on, don’t let this thread die without at least a little help!

I can’t help you with the fin placement, but that sure is a sweet Campbell Bros!
