Response to Tri-X (TXT) in Dektol and in XTol

Chris, XTOL/Tri-X 120 is becoming my most frequently used combo. My tests of Tri-X souped in XTOL and D-76 indicate Tri-X developed in XTOL 1:1 had the best micro contrast in midtones. Tri-X in D-76 had lower highlight values. There are a lot of variables but two tests were consistent. XTOL normal development gives Tri-X a real speed boost(1/2 stop)which builds density of values placed near or on Tri- Xs long toe unlike D-76. XTOL has a little more contrast than D-76 in the highlights. I recommend the development times posted on Kodaks film developing web page. The page lists development times for a CI of .52. I use a condenser enlarger so developing to a lower CI than typically published on film boxes helps acheive a longer tonal scale on the print. I am curious if other can confirm my observation.
