The worst wind-condition ever!! I couldn't build up a good run & had trouble holding pressure in my sail. After some time the top band broke so game over 6.2...... sailed back & changed it for the 6.7 RS6. This was too much. Building up a run with this was terrible.... No run above 60kmh with this one.
When I checked this sail It turned out that my batten was broke at the tip (just behind the camber above the boom). 

Prety bad day.....
