Which lenses in the 58-72mm range are suitable for use with the Linhof wide-angle focusing device, when used on a Linhof Technika V? I'm concerned about physical problems such as filters interfering with the wide-angle device, etc.

In a sort-of related question, what lens focal lengths need a recessed lensboard when used with the Tech V (without the wide-angle device)? I have a Schneider SA 90 f/8 mounted on a recessed lensboard, and from what I've read, this may be unnecessary. Seems to me like it is, though. When I use the 90mm I drop the bed, raise the front standard, and rack the front rail back until it rides over the rail in the camera body. It appears that this barely works, even with the recessed lensboard. I might be missing something here regarding technique. Please comment.
