Quantum or Canon Flash System?

Over at shootsmarter they posted a page on a session with two Quantum flashes.

Might be worth having a look. (requires login probably)

Yup, had to register. They seem to have several interesting articles.

I have tested & made this combo work: STE-2 with Radiopopper PX and a QNEXUS on my T5D-R.
Because the receiver 'eye' for the QNEXUS has to be almost right against the Radiopopper PX receiver 'eye' , I created a strip of velcro with a hole in it. It mitigates light-leaks and makes for a quick removal. I added a few alignment marks to ensure that I can quickly attach the units together. I have only only just tested this and it works great. I have a commercial magazine cover to shoot tomorrow, so I will follow-up with my real-world feedback.
There is a downside: the added velcro makes the Radiopopper too fat to fit into the Canon flash clip/mount, but it still works- its just not securely fitting into the brackets. A simple piece of gaffers tape is sufficient to keep it from slipping out of the bracket.
