Listened to these last night. You did a great job of smoothing out the edits. The 1989 laserdisc mix is really compressed, to the point that it isn’t listenable IMO. I think the original Dolby optical track is much better. There doesn’t seem to be a good uncompressed source for the original 1981 mix.

I forgot how much I liked the 1992 laserdisc mix. It’s a remix, but still pretty close to the original Dolby mix. It’s probably the best overall mix, with good dynamics. The blu-ray remix has a lot more subwoofer bass, but levels are wrong, sound effects are subdued or missing and it actually lacks dynamic range in places. Plus the music has a rather obnoxious echo effect added to the surround channels.
