I agree with Monkey and Longjohn. After years of putting 4 lines on one winder, I've only had a couple of problems with tangles. This happened with unusually high winds and the lines tangled while getting them up.
Like most have said, connect the lines in pairs (right and left), wind them on your winder of choice without loose strands.
A couple of things that I always do with my lines:
- I let my lines out from the handles to the kite, and take the lines up from the handles to the kite. This results in switching the line orientation each time.
- As I wind, I separate the lines through my fingers (like combing) removing any twists as they are put up.
I use Blue line and a figure 8 winder.
