Hi,
The movements I use most for landscapes are vertical shifts, followed by lateral shifts, in order to avoid pointing the camera downward, upward, or to either side. After that, front tilt and sometimes swing. As long as these movements are ample in the front, you can have a totally fixed rear standard and still be fine. I personally prefer to minimize convergence by using shifts rather than rear tilts and/or swings anyhow.
For me, if there was a field camera that was as capable as a Sinar F in the front, yet was a press camera in the back (albeit one with a revolving back), I would be happy.
As it is, I think the Super Graphics and Super Speed Graphics are good choices as far as bang for the buck goes.
This being said, a Sinar F travels surprisingly well in a backpack, lacks nothing as far as movement, and they are very reasonably priced now. My F1 weighs in at about 6 lbs. sans lens. Your Horseman may be just as good for carrying. The drawback is that they are a bit slower to set up than a folding camera, and if weight is a big issue, 6 lb. is prob. too heavy for a camera body alone.
