Testing a new hgh wind formula fin which I borrowed. Do not excactly know the year of process but it's a D2.

i had a 1 hour windor today. Goal was another 50+ evaluated formula session. I had 15 minutes to tune the set on the water untill the wind increased so much I could not handle it anymore more. More wind = higher speeds. Too much wind = no speed.

Fin was OK. No spinouts. A little bit de-powering downwind, because of the twist.
