> Copex Rapid having excellent tonality, is this an exaggeration
No. With SPUR developer Copex works fine and has a good tonality. What you sacrify, however, is the flexibility of conventional films. But ther is no "contrast problem" anymore with that dev.
> When you use a film like ... Copex, or CMS20.., you are working against the film.
Yes, that is right. But the SPUR dev ist the solution at least for copex. It is quite expansive, of course. But Copex + spur is an all purpose combination. You have real 40 asa what is not too far away form the widely used 100 asa film (which may have 50..80 asa in reality). And you have a good tonality.
BTW, I found Agfa Avi Pan 80 = Rollei Retro 80s having not much more grain than copex. But with that film you have a chance subduing it with conventional devs. And you have additional the IR capability. RR80s is my reason for leaving copex.
