Which line lengths and bar do you recommend with which sizes?
This is down to personal preference, but Sky and I use 22m line a lot on sizes 5m² to 10m². The 11m² and12m² are a bit more nimble on 19m lines, though lose a little power. The 3m² and 4 m²are clearly better on 24m lines, as the longer lines smooth out and lengthen the power stroke.
What tips do you have for the different settings?
The Adaptive Tip adjustment gives a light-bar more direct bar choice. A lighter bar is easier on the arms but gives less direct eyes-off feel for the kite.
The front bridle adjustment gives the choice between a more surfy feel and a more depowered freeride-feel.
