Had 3 sets today after adjusting fin to ho's recommendation 6.845, 2.505, 0.780. Out the box the ski was at 6.820, 2.505, 0.785 and I was having to work very hard. With ho's numbers I am getting nice and wide and the ski feels much better in the turns. My coach said I was skiing much smoother today. I will try 6.840, 2.508, 0.775 tomorrow to compare
