Well . . . with some assistance from Jeff Hirsh of Fotocare I traded my 35mm Schneider for the current 32mm Rodenstock. Gain: a 90mm image circle which means I can go very wide (28mm or so equivalent) stitching with my Alpa Max and it's the end of the "blue zone of death". Indeed it's almost (but not quite) possible to use it centered with the IQ 180 without an LCC. The only negative is that it adds a pound and a half to my carry around kit. It looks kind of fragile in pictures but in real life it's quite robust. The focus mount is beautifully weighted.
The results are sensational.
