FL600R vs Metz or ?

When I am working I am carrying two and sometimes three EM5 cameras with FL600R flashes mounted. Using a Black Rapid strap, two cameras hang by my sides and sometimes I hang a third camera from my neck. I probably look like a one man Chinese fire drill!

My system works very well for me and I am able to work fast EXCEPT for the settings on the flashes. The settings are being changed by rubbing against my body. I would place a piece of tape across the back of the flashes but I do make changes as I work. At this point, I need to replace the Fl600R flashes. I have Fl50s but they are too large for good balance.

Soooooooo, does anyone have experience using a Metz or another similar flash with the EM5? Recommendations? One more thing, outdoor fill flash is iffy. Not at all like the FL50.

 

For my purposes, it has plenty of power. The rubbing is the killer! I really don't like to jerry rig equipment used on important events but I will look at the "cover" idea.

Thanks
