I use the Fujinon SW 125 on 8x10. I crop the corners a little when printing and it works pretty well.
I'm not sure about the Deardorff, but on a "Phillips Style" camera, the back can be moved up closer to the front standard and it will focus OK. I also have the bag bellows, but since no movements are available with this lens, it is not any better than the standard bellows.
I had the front standard straight up and down. The issue is with the gear drive pieces hitting each other. Now I see how you have the standard tilted back allowing more room assuming you don't get the supports in the image. I'll try that tonight.
