Stoked on the results didn't expect the alpha to be this high :) Nice to be at Herkingen when it is not overcrowded. Used all my speedboards today 45/50 and 54 today and got them all over 81 topspeed and with 6,4 and the 50 even 84kmh also did the alpha with this set. Turned off the light with Danny got off the water at 18;45 because it was hard to stop surfing
