I use fairly thick stiff bridle line for my leaders a piece of advice from David Ellison, stiff is good it helps to reduce snagging. I started with 4 equal length loops with 5 or 6 equally spaced knots on the bottom leaders they are considerably shortened. On the top leaders I had two knots one at the very end and one a short distance behind it (about half the distance between the break line knots), 90% of the time I flew on the end knot, I used to do most of the adjustments on the break lines. The purpose of the two close set knots on the top leaders was for fine adjustments, if I increased break by setting one knot further back and found it too much I could bring the top lines back to the second knot, effectively giving the break lines back half the initial adjustment.
Having said all that, I have just bought a new set of handles and I am going to set them up with shorter leaders on the bottom and do all the adjustments on longer top leaders, so that we are all singing from the same hymn sheet.
I'm a top leader only guy! Use the factory bottom and made my own top leaders with 5 knots, the middle equals the factory setting, two shorter, two longer, keeps it simple for those of us the don't fly on a regular basis.
