David, I think the HC110 Dil B times are printed wrong for the new Tri-X. Looking at the film box chart it shows 3 3/4 mins at 20C. I have been using the new with my old Tri-X development time of 6 minutes 20C Dil B. The 3 3/4 mins looks more like the Dil A time.

I really think Kodak misprinted these times.

I can't say the same about the other developers though...
