Hi again Bill,
You mentioned that you have had success with the Hotech flattener and the ED120. Do you have any images that I could have a look at. I am honestly thinking of purchasing this same flattener for use with my ED120. I like the fact that it is only a flattener and not reducer. Whereas for the ED80 and the P-Flat4 combination, I like that it reduces about 0.75x.
cheers,
Daniel
