I got a roll of "Jessop" KB17 (label written as ISO 100, but KB17 should be 40, no?). Is Rodinal 1+100 1 hour stand good with this? Or is 1+100 way too active like with some other films? I don't want other developer suggestions, its the only one on hand at the moment, and I would like to mix it with a few other rolls I know are great at 1+100 1 hour stand. I've seen beautiful results I like with 1+150 1 hour stand with Adox CHS 50, which is said to be basically the same. So I was leaning towards that.
