Next time try a Rebuild all rather than pulling EOP up and down. Be sure to post Friday Pic when you get it finished.
And if you haven't already investigated take a look at multi-body technique. I haven't used on a large assebly yet (thinking it might need to be broken down into some derived subs) and would be really interested on how the technique works on larger assemblies. I can tell you it is really great on smaller stuff.
