Because of multiple personality conflicts I wrap a combination of figure 8 and straight, alternating every 20 winds or so. I also like to reverse the lines every now and then by winding away from or towards the handles and occasionally switching the right lines with the left and the top with the bottom. This averages out the stretch to each line and ensures that my lines are always equal in length because it distributes usage (handed-ness and forward/reverse tension) equally to each line, and disperses the memory gained from the line being somewhat tensioned on the winder for extended periods of time.
Really, I do actually do this, and have not had to equalize lines since I started doing this. It is not as complicated as it sounds. You just do it each time you set up and break down. Similar to rotating the tires on a car before radial tires became standard.
