QTR-Quadtone RIP

I've searched the archives and there isn't a recent posting on this
issue?  There seems to be three answers:

(i)   EEM
(ii)  Piezo Museum Bright
(iii) The custom made curves in the files section.

You would think that the last option would be best, but the maker
urged caution when he posted them, and there aren't any reports of usage.

What are people currently using, for those of us still relying on
canned curves?
