Any tried using the 64 or 86 PLM for wedding group portraits? I am thinking about using this tonight in a dimly lit church with the vegabondII and cyber commander.

Would you use AB1600 or AB800? I really want to keep it simple with one light..

PLM directly behind camera, up high (minimize shadows and glasses glare) any other pointers?
Thanks, I will post results and review the performance of the CC on location...

I don't have experience with this PLM, but alls I have to say is roll with the 1600... it's better to have too much power and turn down, instead of not having enough and having to up your iso and get some grain (unless you're into the dirt)
