Hi mate, I have been sailing in this area for 8+ years IMHO
Jp, Choco and flying objects weedster G10 weed fins are all fantastic however they are all a little slow but never a weed problem. Vectors and others with a more upright semi weed shedding rake angle unfortunately still catches our ribbon weed occasionally whilst not planning which can be annoying. Chris Lockwood (tribal fins) has recently included a super weed in his selections which could be worth a look aswell. Hope this helps

I've got a full set of Maui Fin Co (MFC) weedburners that I find great as well.
I sail at pinaroo which is quite weedy and use the 40 cm and 34cm weed fins.
the 34 is a 45deg fin but my 40 is only 40deg rake. Unless the weed is like a brown sea blanket I don't have any problems with it.
I've used it at safety bay without any probs catching weed.
the 34cm in a 60-65cm wide board is one of the best weed fins I've ever had. Better than my leading edge weed fins I think.
Have used a leesacher full carbon as well and that was beyond description(great).
36cm fin that pointed as high up wind as a pointer fin with a 7.8m sail. And no matter how hard you pushed on it, it would not spin out.
Great fins, but you need to probably buy a few and get them sent from Germany to make the purchase worth it.
