Peter, After many years using a Linhof TK I have just invested in an Ebony RSW for landscape work and I can only agree with your comments. One question, I also have a folding Horseman reflex viewer and intend to have it modified by Ebony for use on the RSW. Is the modification to the back, the viewer itself, or the metal frame into which the viewer fits, or a combination of these? Also, do you need to continue to use the extremely nasty Horseman metal spring when using this on your S?
