I've tried the squashed loop with several turns around the center. Too many kinks.

I tried 'chaining' it like they do with climbing rope. A big perk of this method is that it is 100% snag-free.

Lately I've been doubling the length up and then chaining it. Downside is that you end up with the male and female ends on one end. With the 'squashed loop' you can uncoil what you need as you go.

There's also those plastic post things for winding. Don't know if there's anything else to try.

Oh yeah. There's also, ball the whole thing up a la Chevy Chase in "Christmas Vacation". (the speediest of all methods)
