Chooooopppppyyyyyy!! Good fun. Started with the 2017 Loft Speed Blade 6.1 and that worked really well with this board and fin. I love that sail! The wind picked up pretty soon and so I changed to 2015 Speed Blade 5.6. Still don't have it completely right. Need some more time with this. But it controlled the board really nicely. The fin is great. Never used it before so happy with that. Very efficient. I love the board. I think it is capable of speeds of over 85 km/h. Let's see on a good day at sea. 

Performance so so but awesome windy and sunny day with lots of speed addicts. :-)
