Blue skies, perhaps a little too onshore, but really fun to try Dan's RRD twin fin again (I bought the first shape in 2009). After a few runs on each I think we both agreed that in out and out onshore, the single fin or at least the shape of the Wave Cult still worked wonders and felt much quicker. I can't even pretend that my sailing has kept up with any of the recent developments in fin/board design, but I am pretty confident if my board does change it will be an RRD Wave cult again.
