For 30 years I have been using the half wrap (end to end) where you put one end together with the other end, halving the length each time, but less 6" so the ends don't get into the last half. Repeat until the cable bundle is between two and three feet long and tie the whole thing into a simple yet loose knot. Put them all in a road case and done. To unwind, undo the knot and toss it out and it all unravels. I've only had 2 or 3 cables fail over all those years. I'm now using 100ft mic cable and this method isn't working so well for me. Bloody easy to get the rats nest with over 50ft. I'm thinking I should switch to the over / under? I do this with my shop air pressure hose's but have never been that good at it with mic cable. Seems to get into a mess with long runs, but I must just need practice. How are you winding long mic cable runs?
