Yes. Anecdotally Kbr is needed for this low speed film to avoid strikes...
I am seeing some new jargon here. What is "Kbr" and what are "strikes"?

KBr would be potassium bromide, which is not uncommonly added as a restrainer during development. (Particularly useful with very old films in the hopes of cutting down on base fog.)

Got it...the chemist in me was looking for the upper-case B.

Very first shot on my brand new Mamiya RB67, and my first 120 shot all together.
Happy to see that all light seals were OK, lens works great, and the motorized back advanced as it should.
Not that happy with the colors out of the lab scan to be honest, but in a while I'll hopefully be able to afford an EPSON V800 and do some home scanning again.
