My reason for contemplating the grooves, or actually the rods that I was
going to glue on, was not because of any problem with dye on the back...
that didn't seem to happen (maybe I did a pre-soak, I forget). It was
because the large sheets of floppy lith film (12 by 18 inches) clung
unevenly to the wall, also with just a hollow tube the flow on the inside
was too regular, there didn't seem enough turbulence to disturb the
laminar layer -- at least that was my quite inexperienced "diagnosis."

It's possible that upending as Kerik says he does would have solved that,
but in the very short development of lith it also didn't seem ideal.

Then again maybe the dilute Dektol I was using ate stain better
than Dave's developer...
