In my experiments I found that the sharpness was better with the ascorbate than with sulfite. I thought perhaps the fact that the ascorbate is a surface developer which is activated by the p-aminophenol in Rodinal had something to do with it. Xtol, for the same activity, has finer grain and greater sharpness than D-76 according to Kodak.
I use Pyrocat MC Gainer and Sandy described somewhere in apug, cathecol metol with ascorbic acid without sulfite, I've compared the result with PMK and TmaxRS developer in HP5+, the sharpest negative is negative developed with Pyrocat MC with semistand, now all my negative souped in pyrocat MC
