Unexpected wind so I took a chance to what turned out to be a lovely session. In the beginning the wind was really light so I took the 48 SL-X which is designed by Jörg for these conditions. After the break the wind increased a little so I took the 45 SL-X. The difference in speed is amazing, I think it's at least 3 km/u faster on the 10 second run. And besides that it gives more control.
