looking for some fins for a twin set up, for light days on the hogster.

they only seem to make twinfins up tp 16.5 or 17

any decent 18 to 19's out there ??

just buy 2 normal 18s or 19s.
its the same thing

Have a look at the K4 site, not sure how big they go but i just stuck a pair of 16cm fins in my 78lt OES Twin and performance is awesome and only $82 for the pair delivered from Boardzone in NZ.

Flying Objects 165's are a decent size, and they do a G 10 version now too, i can run up to a 6m using them, they have a pretty big surface area which is more important than length.. well thats what the ladies tell me

Maui Ultra Fins makes 17.5 cm twin fins.

do you really want fins that big? 17 is the MAX i'd go, even with a 100 litre board

I recently tried 17s on the chopper 90on a half mast to head high day. They worked
Well. Board had more of a single fin feeling but was plenty loose still. This might be my choice for bigger days and or 6.0 weather. I reckon having some 17s and 15.5s to switch around is totally worthy

I used to have a pair of 18's on the Hog she trucked up wind, planed super early, had heaps of drive and was as loose as a goose.

That was way back when I was a FAT FECKER
