Just how obnoxious are recessed Linhof boards to use (Copal 0)? It would seem that there is little room to do anything but are they unuseable if that is the only choice, should they be avoided at all costs? Is the 11mm recession just as bad as the 19mm? I notice that most of them are of the offset type, no doubt to allow more finger room, will they all fit through the neck of the camera or is the amount of recession sometimes blocked by the front standards design?
