One other quick observation before bed: There have been reports that the Einstein doesn't play at all well with Pocket Wizard Plus IIs. Some individuals are getting terribly unreliable triggering, even at very short distances, while others are reporting no problems at all. I decided to try a PW test.
I mounted a PW II in a tilting flash shoe which was screwed onto a length of 1/4-20 threaded rod which, in turn, was slipped into the back opening of the Einstein's umbrella tube. That put the PW in very close proximity to the body of the light. At distances available to me this evening (up to 25' or so), I found a camera-mounted PW would trigger the Einstein with 100% reliability. On the other hand, my Sekonic L358 with PW module had very poor success in triggering the flash from distances beyond approximately 8'.
The setup:

Too soon to draw any firm conclusions. More testing under better controlled circumstances will be required. Of course, in all probability, most Einstein owners/users will rely on the Cyber Commander and Cybersyncs so the PW issue (if there is one) will be totally irrelevant.
