In reply to Dave Perry:
Only on my 10m rigging rope wich I usualy alp coil anyway and a chest coil for shits and gigs.
Alp coil gives you a fat rope hoop you can throw around you or body of your pack and take off with out having to untie anything. It's also dead simple but spooling rope off courses twists so you need to unwind it.
Over under coil isn't as simple but would give all the over above advantages without the spooling issue.
Havn't done it enough to say weather you could belay stright off the coil without hold ups but it could be a possibility.
