I haven't jumped. The main reason to switch is that Superfly is much faster, but folks are having issues with materials looking different in that iteration of Superfly. I don't use Superfly at all except to test my freebies. The HUGE downside is that most of your python scripts will no longer work because Poser 12 uses Python 3. That includes the DSON converter that lets you use Genesis figures. So if you rely heavily on scripts, you will have to switch back to Poser 11 to use them.
