At the same time, the foreign stereo track is missing a couple of the mono additions. The added breakdown noises to Red Leader's X-Wing crash are not present.

I still have no idea what track you're referring to. Can you elaborate?

Hmm . . . well, just from the few comments that have been made here, it is clear that opinions on which mono additions are important to the film and which are not vary widely. Obviously there will be no consensus on this issue. Nonetheless it may be helpful to determine which ones are generally viewed as being the most significant so I know what to focus on. Keeping in mind, of course, that I can't possibly include them all, and that my own personal preference is likely to play a part as well.

I'd also like to hear some opinions about the two possible methods I outlined above. Which do people prefer: the 70mm with some things added to it, or the '97 SE mix de-crappified? Either one is a viable possibility for a potential hybrid version.
