Since I just invested a small fortune into my new 600 EX-RT flashes and plan to use them off camera a lot more,
I am reevaluating my set up.

I will be using the ST E3 RT transmitter on camera with at least one flash mounted to a monopod with a flash mounting bracket and an umbrella carried around by an assistant.

My concern is that the shoe mount of the flash will be getting a much greater workout on the monopod than it had on camera or fixed on a stand.
My assistant sometimes is not the most careful person. I figure the umbrella will help protect the flash in 'drops' but should I worry about the shoe mount getting a workout and becoming loose or broken with this set up.

Is there a better method?
If I could avoid using the shoe mount off camera all together this would make me feel better.

Suggestions are appreciated.

Thank you.
