Have been watching your original XVID edit for the 3rd time today, and was once again marvelling at the work you've put into this. I'd love to see the proper DVD version but alas our download limit is only 3GB, and then we have a 'fair use' policy which means I cannot download all day! AGhhhhhh!
Anyway I was watching the part where Ben is deactivating the reactor, and for some reason the sound effect used in the original Flash Gordon Republic serials for the sound of the ships flying popped into my head! (as it does.....!!!). I think this effect would really bring the tractor beam alive - seems to fit the visual perfectly. It would also be a nice little homage to Flash Gordon, which of course Star Wars was based upon...
I know you've 'locked off' your edit now, but if you did wish to use it as a last minute sound FX tweak I could mail you the soundeffect WAV next week.
Thanks again for what is clearly the definitive version of Star Wars now :)
