Really happy with set up now. Modified all the battens to have the trim I was looking for and seems to be going well. Certianly against Kai I am going better than before. 

I had a max speed of over 38kts which I think is maybe a record for me on the medium board.

Then I had a bit of a race with Bjorn and he smashed up. He was on speed gear, but over 250m he was over 2 kts quicker... still work to do.
