You don't want to get too close to a balanced load otherwise the arbor may run in on its own.  It's especially a problem if someone takes off a couple of lights without compensating at the arbor.

Zat helps a lot.... thanks.  Mine is attached at the bottom only, and
what you say about it being slightly out of weight makes perfect
sense. Let gravity be our friend.  I'll have to inspect and do a fresh
calculation.  Since there's no hand line, it's not really been
possible to really tell if we're in- or out-of-weight. - Jon
