D23 and D76 have the same sulfite content (100 grams/liter), and I have developed TMX-100 in both D23 and D76 diluted 1:1 and cannot see any difference in sharpness. Diluting 1:1 effectively halfs the sulfite content. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> >

Sometime try Tri-X, HP5+ or FP4+ in one of the pyro formulae. You might see a big difference in sharpness
