In reply to sparkass:
the second point will be him backed up with a gri gri, or tied into the rope short.
When jugging you should tie in short (tie a know on the bite and clip into harness) so if your jugs come off you wont fall all the way to the end of the rope.
A gri gri can be used instead, so if your jugs fall off you fall onto your gri gri. Gri gri has the advantage that after a while it starts to self feed with the weight of the rope and will automatically start taking in slack and hence your continuously tied in short.
