Any reason why you switched over to the tubes from the SP445 Alan
Mostly because I can develop more than one sheet of film, simultaneously. After some calculating of the timings, I've found I can run 3 tubes at once.

Although I am assuming there shouldn't be, have you noticed any difference in the negatives developed in tubes vs the SP445
Not as far as what the EMA technique provides. However, and this issue is unrelated to EMA, I have occasionally had very faint lines (I have the original style film holders) on the neg and/or small marks along the film edge where the film slips under the tabs with the SP445. Negs come out of the tubes revealing beautiful even development.
I watched Steves video showing the construction of the tubes and I have to say it does look interesting.
