Hello, After much research and worshipping of the Large Format forum, I have pre tty much decided on the Arca Swiss 6x9 FC for my new project photographing Main Streets. My question is, do I get the regular F Compact, or the Metric, which ha s geared rise, fall & shift and weighs a bit more. It also costs $700 more. Is the convenience of the geared adjustments worth that much? I have an arthritic finger and need controls that are easy. Has anyone used the locking adjustments on the regular FC - are they simple to use? Do you turn a knob or flip a clamp ? Obviously I have no access to one of these cameras. Thanks.
