I think it was suggested in another thread that one should try adding a wind deformer (force field, whatever they call them), to see improved dynamic results.  I've had tolerably decent dynamics with wind, using the Alyson Long hair in a 30 frame simulation.  Perhaps you could open that one up and study its settings.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
