In the square format I have three SQ-As. I keep a waist level finder and crank on one of them all the time. With an 80/2.8 is makes a nice compact set-up and doesn't weigh too much. The speed grip is really necessary if you are shooting at eye level with prism finder. I use the waist level finder more with the SQ-As than with the ETR series or GS-1s because it's less awkward with the square format. I normally shoot medium format at a slower pace. Motorized advance would be better for me if 220 b&w films were still being made.
