I've been using HC-110 at 1:47 from concentrate for Tri-X, HP5+ and APX25 with no unusual results. I haven't tried 1:100, mainly because I use a small tank and you have to be sure to have enough developer in the solution for the film. I think you need at least 7.5ml of the concentrate per 36exp 35 or 120 roll (check the data sheet), so you'd need at least 757.5ml of working solution at 1:100.(posted 8748 days ago)I think Adams discusses the use of very dilute HC-110 in "The Negative", using it as a compensating developer to reduce highlight density.
I've never tried pushing Tri-X to 1600 in HC-110. I find my EI is around 200, so I'd expect to lose a lot of shadow detail at EI 1600. Your milage may vary of course.
