There are variations of D76 that omit hydroquinone. If you use lots of
developer, it might be worth your while to mix it from scratch. Xtol is an
excellent developer that I used happily for almost 3 years until
experiencing Xtol sudden death syndrome. I no longer trust it and have gone
back to D76 and DDX (expensive Microphen). If I were to continue with Xtol
it would have necessitated snip tests before every developing batch, and I
know myself well enough to anticipate one day skipping that step, possibly
to subsequent sorrow. There is lots on this issue in Google groups.
