I am a field service turbine mechanic. When I get to a job site and my boxes are unloaded and the game plan is hashed out, the first thing I do is figure out what tools I am going to need. Not just for one or two jobs. I hate going back and forth from a tool box. I plan it out, and put everything I need (within reason) into a tool bag. Well, I am please with this bag... plenty of room, plenty of pockets. Nice and sturdy, good balanced feel.
