Like I have written many times in the past, I find street photography a pleasure to do with a Hasselblad. The WLF is really wonderful to use, in terms of approaching people, composing but also because of the lower angle which I love. Any other finder would be wasted with me.
I usually use TriX 320, mostly because of the look, but FP4+ is easy to use in the warm months here in Crete. I have even shot with PanF+ handheld.
Only trouble with the Hassy is the mirror sound when you want to be more unnoticed. Not trouble on the street where there is usually lots of noise and distructions but it would be difficult inside a quiet place. That's where the TLR wins.
A RF is even more practical inside a place where you take photos sitted as the WLF is not very practical there.
