I am not familiar with that exact kite but am familiar with crossover.
I have not heard of using it to adjust flying characteristics?
If the knots you refer to are on the bottom up from your brake line up I suspect they are simple there to adjust over all brake tension and only your
brake lines go on them ?
The crossover should have no influence at neutral. It only enters into the game when you turn. Or at least that is what I used to set for ? I think I
found if it does influence at neutral then the kite gets wonky ?
