birdlady, I've been wondering if there are only two bag swingers (Ami and Cirie for Malakal and James and Natalie (maybe) for Airai) and that they have to rush back and forth trying to keep all the bags swinging.. perhaps because they're unreachable if they stop swinging. (don't know if i said that clearly). THat would explain why Cire and Ami switch places.

Any chance this is a combo RC/IC?
