I was looking at several 2 bath formulas in Barry Thorton's website and I'd like to try one or 2 of those.
I wanted to start with divided D-23/DD-23 Found HERE (kodak's formula and modified)

My main concern is that I have phenidone at home, but not metol.

Can I replace phenidone for metol? If so what is the equivalent in weights from one to the other?
