Over the past couple of years I've been trying a few different fins on my Angulo Shaka XLT. I have finally found one that I'm going to keep on there for a while. The right fin can make a huge difference in the way your board feels and performs. Fin design is all about acceptable compromises between stability, performance, and speed. It's also a little bit of a black art: one part science, one part anecdote, one part looks, and one part personal feel. Granted, my review won't be very scientific, but hopefully it will give you a place to start if you are looking for a good fin for downwind conditions. I might do it as a video so I don't have to type so much! Stay tuned!
