Eclipse 2008 bar (50 cm?) with the line extensions attached. I used the knots closest to the kite on the bar and the 3rd knot from the end on the kite's rear pigtails.
Ive been using the knots closest to the bar at the bar and mid knot at the kite which = what your setup was.
I like the 9m on 20 mtr lines and it seems to get going in the lite fine like this and it doesn't pull down wind as much when powered and tends to point higher upwind in all conditions.
I have only had a couple of sessions on the 9m . I like its all round performance, and really rate it it for down wind wave riding with a surfboard in lite wind.
And like you I pay for my kites and ride only what I like.
