Hope this pic helps,
The orange leader i currenly use with the orginal handles.
The original leader (black) can also be used for achieving this length when larksheaded at an "extend" leader (white) between the handle and the original leader.
And It also prevent wear at the handle end, just replace the exender leaders...
This one i got from this forum,, stroke survivior mentioned this if i remind it well
What matter the setting i am using the knot, just in between of a roaring kite when flying fast forward and falling down when hovered LE up.
I.o.w. the kite should be silent as possible when FF flying but still hover LE up without walking backwards.
It depends on the wind to set this knot but ussually it;s the third or second knot from the end of the top leader.
On my other handles this is exactly 8.5 inch from the handle end and flies as a dream.
Keep in mind that this is my setting a.t.m. and may not work for you
