The idea behind an INC file is so you can put commonly used code for multple macros as I understand it, and it will get pulled when the macro first starts. From that point of view I would think there would be no/slight difference in pull a few large INC files VS pulling a lot of small ones, outside of additional lines of code to include and call the files of course.
Though I do know that the more battle spam you are showing the more lag you can generate. This gets worse when you are logging, and moreso when you are parsing. I recently went through this with a guildie whose log file was getting into multiple gigs.
Just thought I might mention that incase it was something you may not have looked in to, if you are using logs.
