About the only bad habit I've found with MC110 is the edge of the paper scalloping after it has dried. I didn't really notice it until I had a blank sheet of paper go through my process that I decided to use for focusing and framing in the easel. It wouldn't go in the catch slot on the easel. I don't recall ever having this problem with other papers to the same extent. I'd imagine this would also show up in the mounting process if you don't trim the edges of the paper first.
The second bad habit I've run into and it has caused me no end to grief, is that with the Print WA developer, there seems to come a point in developer exhaustion where one print is fine and the next is three stops under-exposed. Instead of a gentle slowdown in development, it seems to crash. Am I off my rocker on this one?
