yep correctly coiling upwards of 30 cables (PA and backline, mics ecs, lights etc) is a non starter at 1am. I know im going to get shot here but but I put mine togeather by grabbing both ends, halving the length, halving again and then tying a very loose knot in the middle, that way they don't get all tangled up in a box of leads, can be extracted easily and if good quality last for years.
Weirdly the guitarist who only "correctly" coils 2 of his precious leads is constantly breaking them, then nicks mine!
