Hmmm…honestly, I think I prefer it without the sound. Just like how the music drops out at that point, I think the line has more weight when there’s nothing to distract from it. Obviously, that comes with the huge caveat that the original edit can be made flawless; barring that, I think the lightsaber sound is a clever band-aid over it.
That said, I agree with oviniboy that it doesn’t quite sound organic to the scene yet. I think it needs more bass maybe? Just something to give it more “oomph.”
Which actually leads into an important question - how will the lightsaber sounds change as a result of the new “cracked crystal core” concept? Will it be modified to sound closer to Kylo’s saber, with that buzzing/motor quality to it? Maybe a blend of Kylo’s saber sounds coupled with the original Luke saber sounds? However that goes in V2, this new effect would have to match.
