Last year, I made the shift in battery powered strobes to the Profoto B1 system including the TTLc remote control.  Of course it does more than TTL, you have full manual control and access to the incredible assortment of Profoto light shaping tools.  Reviewers around the world loved the system and pros such as Joe McNally, Dixie Dixon and Tamara Lackey have moved to the Profoto system from alternatives.
