TC,
Have you operated a 206 or 206L (this event was from a LongRanger, not a jetbox) on drops? I've never found it to be short of TR authority so I'd disagree with your assertions there, but jumpers generally need very close control. The driver's side doors should never come off, all jumps from the one side (away from the pilot) to ensure lateral CG isn't put at risk.
Like this, from an N reg R44
