Thanks SCL, AJG and orsetto for your additional contributions. Choices, choices...! :-)
As far as I am concerned, going back to the Hasselblad 6x6 system is not an option. Too unwieldy. I'd rather tinker with a high quality, slo-pho alternative to the ubiquitous cell phone/P&S shooting. Certainly, a TLR is not exactly pocketable, LOL, but I like the idea of a neat and restricted package, with only the most basic of parameters to select from (aperture and shutter speed). For me, it promises a welcome challenge, entirely focusing on composition/decisive moment. And a 75/80mm field of view is what I feel very comfortable with.
