Pleased to see you are following the thread, Bob.
I like the MFM and particularily the outflanking bit and use that for my 35mm and 4x5 enlargers.
When I got my 8x10 enlarger I was forced to the 00 and 5 blue/green printing technique and I find it hard to understand and reconcile the common principles.
Still as you point out, the print is the important thing and how anyone gets there is as valid as the next.
