Have had this fin out twice now and am greatly impressed. On my local water weed is a real problem and and getting a good fast weed fin was always a problem, so after getting a lessacher 24cm chameleon I ordered a 32cm duo cut weed.
Fin is super solid - fully loading up the fin has no hint of spinout (both upwind and on screaming broad reach.) I even deliberately tried to induce spinout with no effect.
Using a 114 slalom and a 7.5m sail was a perfect match for this fin and even got a PB for that board.
Once again Wolfgang was easy to deal with and is always willing to answer my stupid questions.
So if you are after a fast solid weed fin - try one of these..
