I use the TT5 with Sunpak and vivitar flash units. I use them with cords since the shoe mount won't trigger them. But I have to tell you, for $74 delivered, the Yongnuo 560 II is a absolute awesome unit. I'm serious going to check out the 622N triggers if they ever come out, I am that impressed with the flash. I own three PW TT5's, a TT1, AC3, and 5 plus III's so thats a fairly bold statement for me. Lately I have been using a Wein IR optical trigger with a Sunpak 383 or Vivitar unit with a optical slave plugged directly into the flash units jack. I can carry a flash unit with me, the Wein and often my X100 which is a small package to tote around yet gives me all sorts of lighting options without needing cords, triggers and other stuff. Pretty uncomplicated too.
The PW TT5/TT1 stuff is close to hitting CL or Ebay. I don't use TTL flash much preferring manual and the Plus III's rule in the studio and work for manual offering good group support .
