One sensible addition to make is to replace the standard loops of line through the top and bottom of the handles, with some lines that is knotted at about 2 cm intervals.

This allows you to adjust the relative lengths of the upper and lower lines in order to give yourself more forward or backwards (i.e. brake) movement. This is useful for two reasons:

1. You can adjust the lines according to wind strength - more wind, lengthen the top lines, less wind, shorten the top lines. Or find a combination of lengthening/shortening the tops/bottoms to get something you like. So long as it's the same both sides.......
2. Usually over time the top lines stretch - by quite a lot (bear in mind that the top lines take most of the strain when flying). As Revolution lines are meant to be exactly the same length (all 4 of them) this causes problems flying over a period of time. Therefore being able to quickly compensate the line length whilst flying means you don't have to resleeve the whole line set (who wants to do that for fun? Especially when there is a good wind?)
