Only 10k  when I arrived so rigged a 9.5m and went out for a couple of hours, got planning but felt well underpowered. At around 3.30pm the wind picked up to 20k and I felt way overpowered but opted to stay on the 9.5m. If I'd had more time, the 8.6m/W58 would have been fun. Used my new X9 xl boom with a wide tail, could not get on with it at first, took a couple of hours to get harness line length and position correct, and I had to alter my usual stance. Good session.
