Dispite the rain a great surfday! Martin offerd me to test his fin. And at the end of the day I didn't gave it back, wow this is something else. I tried the thin profile which isn't ment for open water but it worked great. The fin made it like there was no chop anymore. Lateron I switched to the SS23 to feel the differences. The SS feels much harder and chop feels higher. The Ufo is al least 1km/u faster in the runs. Besides fin testing it was a great surfday with a lot of surfers. Made some km's, which I needed a lot after 3 weeks of no surfing.
