I don't let anyone coil cables. I suppose more accurately, I tell them not to.
As long as everything makes it back into the truck at the end of the gig, I will deal with the cables.
I will wrap the cables my way, and it's easier and faster for me if I don't have to un-do cables that have been wrapped wrong.
It's a therapeutic couple of hours and I can inspect them for damage along the way.
And I can make sure that the 20's are binned with the 20's, the 25's are binned with the 25's, etc - rather than being surprised when I go to reach for a cable at the next setup only to discover that I've just run a cable that's 5 feet short.
I'm glad to let the guys help with the heavy lifting, in and out, but leave the cables to me - they're mine anyway.
As long as they will take the heavy stuff _to_ but not _into_ the truck.
Stuff fits in exactly one way, and I'm tired of having to unload everything at the end of a 0300 load-out because stuff got put in wrong...
This inevitably happens on either the hottest or coldest day of the year... Bonus points if it is raining or snowing...
This is the only way (to maintain your sanity) with cables.
