opinion , please

An 8 ft by 23 by 3 1/2  quad  for a big guy , opinion on what " size " fins to use , thanks .

I bought a packaged set of black honeycomb FCS quad fins marked “large” for my 7’-2" x 23" x 3 3/8" with wide tail, and I love them. Bet they’d work great on your board. Fronts are PC-7s, and rears are G-XQs.

Simon Andersons for big guys.

Like me.

Thanks guys .
