i use the cambo wrs with SK43 and 120 and Rod70 all in T/S mounts. the back has +/-15-20mm rise shift both ways. I also use a IQ160 and find the focus mask, where you shoot and check what is in focus, then adjust for the next shot. other than operating tethered, this is the best way for me. some have tried live view, i have not, but it is there. previously, i used the Xact wtih a digital back and ground glass adapter. had all the movements but you could simply not see what was happening on the tiny GG. the beauty of the 4x5 ground glass focusing is not part of the digital back approach, sadly. I think the Phase IQ backs are very useful for tech cameras, probably would have made the Xact a keeper. shooting tethered offers the use of a large monitor and also focusmask via capture one.
what one really wants is a large, at least 4x5, live view image. with the IQ, you get a pretty good, but small and dead, image
