I'm starting out with (2)FlexTT5s and (1)MiniTT1. I may acquire 2 more FlexTT5s depending on how things go. Right now I have (2)SB-900s, an SB-800, a T5d-R and a Trio. If these PWs work with QFlash, I probably won't be buying speedlights soon.
The lack of a fourth group is disappointing. I chiefly want to work with a Key, Fill, Hair, and Back light. In any event, I could set a QFlash up as a bare bulb back light on manual with a PW Plus II.
Right now I have one mid sized soft box and three umbrellas. Until I get a portable soft box, I will use ball bungees to fix a speedlight to a speed ring, Strobist style.
