Then why there are Selenium, Cool, Warm, Sepia, Variable Mix, Neutral
inksets present around?

Jeff, first of all let me tell that I'm very grateful and greatly
appreciate your efforts to design this workflow and I use it with
pleasure. I want to thank you (and many others that share their hard
work with the rest of us). Please understand that I'm not trashing your
wonderful workflow just looking for a less ink laying alternative (the
wavy prints I get using light papers - EAM and HPR max. 192 gsm - are a
concern to me).

Best regards,
Loris.
