Thank you Dylan. The new version looks so much better. Especially on the phone, that makes it so much nicer. I love the new features too, they really help to see more details of the session. 10/10 for me.
I'm going to ask the obvious but have you tried to reduced the stab angle? Have you checked you sail trim (different from going upwind or downwind)? And last, your front foot strap position. It's probably worth moving it forward and have a wider stance (more control) if you said you want to do more reaching.
I agree with the others about a shorter fuse as well. It makes life easier on the reach.
