Managed to finally get out on the single fin (home creation), and it is without doubt the smallest piece of foam I have ridden to date. It still managed to paddle pretty well, and the undersized fin, made it feel so loose, but still enough speed to go flying down the line. Hopefully get out again, but this time run the quad fin rounded pin (5'11 Seedhouse), for a bit more drive as the late afternoon starts to work closer to home.
