Diaphragm vs. Borg and Beck.............
Well I had no idea what was going to transpire when i asked my question. Lol.
So my original postulation of, "neither side can agree on JACK!", has indeed proved to be true here on FABO too......
As mentioned I went with the McLeod diaphragm, scalloped plate, etc. Somehow I think it wil survive behind my 273. In fact i think it may do okay behind the eventual warmed up 360. Time will tell!
