Keep in mind that contrast is increasing through that series of developers. I have used Technidol, D-76, HC-110 and D-19 on tech pan. Using Technidol gives negatives with a useful contrast range. D-76 also gave contrasty, but printable negatives. D-19 gives extremely contrasty negatives (basically two toned). I had bad luck with HC-110 giving me an extremely high base fog (I shot EI 100 and used dilution F for 7 minutes. Very high base fogging and blocking out of highlights). Good luck.
