I have been lazy and using DDX for rotary processing. I have not been making big prints but I now want a developer that will give substantially finer grain and smoother tonality than DDX does. DDX seems to produce rather coarse negs when used with constant agitation compared to intermittent agitation in small tanks.

Xtol 1+1 is a good bet and I am familiar with this developer in small tanks, but have never used it with constant agitation. Comments?

What other options might there be that would be compatible with a Paterson orbital, i.e. I will be using only about 300ml of dev in total for 2 x 5x7 sheets so concentrations and total amount of concentrate in the 300ml could be relevant. Thoughts?
