B/W film in summer for urban documentary project, and come kit critique please

[RezaLoghme]

As the Hasselblad kit is gone, I am getting ready for another trip, this time with my Leica gear. I am somehow leaning towards my R6, despite the fact that it is fully manual. Maybe that is where the 28-70 vario Elmar comes into play.

Then again, I might give my Leicaflex SL a chance to prove itself.
