here's a pic i found where the weight had strangely sheared off completely but the pulley still worked-

you can see the rubber 'doughnut' which usually separates from the outer ring, allowing the inner lugs (obviously broken off in this pic) to smack against the spokes which then results in this-

i wouldn't like to guess how long it would take to chew right through those spokes...
though without the damper on, i would think a lot longer. then of course you have the issue of no damper, so excessive vibration on the crankshaft. so going back to my original question, what would be the lesser of two evils?

Hmmm, presuming the pulley is bolted to the crank via those spokes. The rubber ring is adhered to the inside of the pulley and has the metal ring with lugs adhered to it. Then without the mass of the weight, I think there would be less resistant inertia to hold it back. If I'm right, then how much of a margin that gives you I'm not sure.
