I to have tried Xtol and many others. Yes they are easier in one since but fussy in another. The 2 bath seems to be almost "fool- proof"...I suppose that only a fool can use them..I'm simple minded. I see many comments related to "speed increases" of developers. I have yet to fully understand the principal. Anyone care to try a simple explanation? Also, how would I know if my negs exibit a loss or gain in speed while looking at them on the light table.(posted 8618 days ago)Thanks for all who have posted, Don
