[quote="David A. Goldfarb"]Inspection is a good approach. Base fog will be high, so you might want to add a restrainer like benzotriazole or increase the level of whatever restrainer is already in the formula you decide to use. For Pyrocat HD, ask Sandy.

I second David's suggestion to add a little Benzotriazole. You might try something like 5ml per liter of developer of a 1% Benzotriazole.

This is one application where I would not recommend Pyrocat-HD. The b+f, which is already very high, will be increased much more with a staining developer than with a traditional non-stainining developer. Better to use Rodinal or perhaps D76 1:1.
