I am very happy with the MiniTT1/AC3 on my camera and three FlexTT5's for the strobes. I have AB's that I use with AC9's for studio shoots. I disable the the automatic trigger of the AB's from other strobes so that everything is controlled by the AC3 using two or three groups.
For other shoots outside the studio and for the portability, I use an SB910 and SB600 with the PW's. While I tested it just to show myself that it all works together in TTL, I still prefer to shoot in manual. Then I just adjust the levels on each group with the AC3.
