Thanks, Mystic - I REALLY mean to try that out (and thanks for clarifying how to do the save), when time permits.
If I can get that to work like that, then I will most likely choose to use that approach, as it would cut down on instances of Kontakt 5, which lessens the Sonar memory footprint, making my computer happier, and spreading joy throughout the land. (Sorry, got carried away a bit at the end).
I DO like the memory savings of that - so I will post back when I get a chance to try it out.
The sections hybrid approach sounds pretty mentally useful - I always give instrument its own audio track, and suggest you think of trying to organize it that way - and creating sections through track folders and grouped faders and such. I think that would maybe give you a bit more finite control over relative balance within a given section - just a thought.
