When i arrived a light breeze zo i rigged up the foil with the 7.0 Warp. Suddenly a lot more wind so started with the 90 liters Angulo and the 7.0 warp. After 10 minutes no more wind so i had to swim a lot. Back on the shore i went for the foil again. 10 minutes later too much wind for the foil and the 7.0. So switched again to the 90 liters slalom.
