Best Metz flash system for Leica M7



I'm looking to buy a Metz flash for my M7, and have been hesitating between going for a 44 series or a CL series.

Only thing is 44 series doesn't swivel 360°, and also is right above the lens so there must be some red-eye effect there.

Anyone with experience with CL series? I've never owned handle-mounted flash.

What recommendations to pair up best with M7 capabilities?

Looking for good flash capabilities, not necessarily high guide number but light and flexible

Thanks for your input
