Rigged 6.7 and started out with the 35cm Tectonics F1 Falcon fin and did a few fast runs but wind picked up so changed to the 30cm version. Immediately felt faster and freer! The fast runs where when I got a gust going very broad and the whole rig and board lifted and I relaxed and 'flew the fin' on the edge of disaster. Loving my speed sailing!
