If you have all the smoothness you need, I wonder if 2 more dilutions would
improve the situation enough to offset the additional work in profiling and
ink mixing & loading.

If you use the machine regularly and only print matte, the UT1 toner would
be an option.  For just minor toning R800 blue and Red are interesting
options also.  However, for significant cooling and for the more control,
the LC (LLC better) and LM are needed.  That, of course, introduces the more
complexity in profiling, but it's not bad.

It's really rather subjective.
