I've used divided D 23 as well with very good results. I was using the recipe and procedure that Barry Thornton wrote about in 'Edge of Darkness' if i remember correctly. It will give you nice tones and highlights, and the working solutions last quite some time. I would still be using it now, but I find that I like the results I get from PCat HD in roll film. I have not used D23 for sheet films. Good Luck!
