Fin gurus need some advice:

9'1 Classic Malibu HP, triple stringer, heaps of rocker & tail lift, channel bottom with FCS thruster set-up - goes like a rocket. Apparently made for one of the Classic Malibu pro riders to take to Nationals at Yalingup.

Going through key hole this morning knocked out a FCS FG 5 side bite - didn't realise and thought it felt a bit looser than normal.

Now need to replace the fins hence my question - what size / model do you any of you ride?

I'm 100kg.

Cheers

In small.stuff I use shapers Jackson close 9s with a tiny shark.fin. Over more drive out of it and the little one keeps it super loose. When it gets a bit more punch/size I have just started using shapers am3.don't need the drive so much and still want to keep it super loose.
A bigger guy I know uses pc7 in the sides and switches between a pc5/pc3 as the centre fin and he loves it.
