Hi,
Overview:
My current flash setup comprises of the 580exII's and PW miniTT1 & various TT5's.
I use the Sekonic L-758DR to remotely trigger the flashes to ascertain correct exposure settings. At the moment all seems to be working perfectly well.
I use various 'borrowed' camera-bodies (7D/40D/5D/30D/6D/60D) from fiends for photo-shoots that they need me to attend, so I take along my flash gear and triggers. I do make sure that everything is calibrated before any given shoot with the Sekonic/colour-checker passport. [Don't ask me about batteries!
]
Dilemma:
To take my photography to the next-level what would you guys choose between:
a) 4 x Canon 600ex-RT's & ST-E3-RT combo
or
b)1 x ProFoto B1 (various modifiers/reflectors) - hmmm battery-pack 
I haven't found any info' on the ProFoto being compatible with the PW's.
The PW site does list the 600ex-rt as being compatible with both the mini & the TT5.
Yes, I have experimented with firing my current flashes at a distance of 60m+ - but only as an experiment to test the capability. The 30m distance offered by Canon is more than adequate - never shoot studio-based in excess of 10m anyway.
I leave for Bulgaria for a 3month break within the next few days so I will be able to experiment tirelessly with any new purchased kit.
A btw fact:
Yeah I know, I am currently camera-less. I travel around quite a bit, so to get a good deal at an airport will be quite easy.
I need the GPS & Wifi capability for what I shoot -> 6D
I love the silky-smooth quality of images that the 5Diii produces

Speedlight for now, with an AB800 in the very near future...hopefully.
