I’ve pretty much come to the conclusion that the subs on Tech prints were different than typical prints, probably due to the fact that typical prints are one or two generations down the duplication chain from Technicolor, and each step on the way makes the letters look thicker.

So, in my opinion, you should first decide, am I aiming for Technicolor or Eastman? If Technicolor, use the subs Harmy already made for 2.5. If Eastman, use the subs I provided. I won’t be making any adjustments to those subs, aside from color, any time soon.
