Windy all day but unfortunately the wind dropped to 15-20 knots, square and gusty the minute I got out in the evening. Rigged 7.1 thinking I'd have plenty of power but would have benefited from a bigger sail. Nevertheless happy with a 33.8 knots peak in marginal conditions. Had a couple of runs with the w54 & Black Project Type S 26.5 at the start and the rest with the iSonic 107 and the new Black Project Sabre 37.5. Great combo. This fin flies and accelerates like crazy
