I have used their wave weed multi fins for a few years now and they are great for weedy winter Dutchies.

I need a set of slot box twins anyone interested in making up an order?
they are worth getting if you need weed fins. I've got one of the ONO weed fins for my mistral freestyle wave board and it's probably the best weed fin I've used for this style of board.
The Koi weed is good, but the most impressive for freestyle and B&J(not 100% freestyle)...is the Naia! This is fast fin and at 18cm got a lot of erea to fit a 5.7 and freestyle!
