I think there are a lot of advantages for your particular set up by using
Best Color Proof. You have support for both printers and many more , full
linearisation tools, and some very useful colorimetry tools/functions. You
can now mix and match on an object by object embedded and default by color
space methods, completely adjustable ink tank black setting to reduce
metamerism issues (accepting the black ink color of course) and more.
The paper itself seems to play into this a lot. For example people having
problems with green prints on the HP 10-50 find by switching to Epson photo
paper it printed out perfectly using the internal calibration tables and the
included ScanVec rip.
The linearisation of the printer can indeed reduce color shifts yet it's the
profile of the already linearised state that corrects for color derivatives.
Some people prefer to linearise, and correct (visually) this linearisation
before profiling. For a known output , it can target the output device
perhaps better on surfaces that require special spectros to measure.
