One does get the sense that he's more interested in talking about his cameras than, say, shooting _Playboy_ centerfolds. I was pleasantly surprised one day, when he called me personally to double check some detail about some lensboards I had ordered.
Incidentally, another potential indirect weight savings with the Gowland monorails is that you can use a single-tilt tripod head (fore and aft tilt only) and level the camera horizontally from the tripod block, because it uses a cylindrical rail. There are Linhof and Reis heads of this type, as well as many video heads. I even toyed with the idea of going headless for a while, but decided that I needed the fore/aft tilt often enough that it wasn't worth it.
