Looking at the effect, I think maybe it could/should be a little more subtle? In keeping with the audio mix also being more subtle. Maybe less of a constant crackle? Not only would this be less work (from a practical standpoint) but if you choose which shots should have the blade sort of shimmer/undulate with energy every now and again, it’d make it obvious that the reforged blade isn’t fully whole, but not as in-turmoil or disturbed as Kylo’s is.

Right now, it looks like its’ effectively the same energy moving through both blades, and the idea here is, from what I’ve gathered, that Rey’s blade is SIMILAR, but not exactly the same on that note. She did a better job fixing the blade that was broken (LOTR, I know, but still) and I think the best way to get that across is by only subtly manipulating the image - essentially, every 5-10 seconds or so there’s a ripple of unstable energy that crackles and rolls from hilt to point and back again.

LOL, I just realized that the effect I’m kind of describing is (and this is for the old-folks here) a faulty vertical hold on a tube tv. Not EXACTLY that same effect, but something along those lines. The picture is mostly stable, but it jitters some, and every now and again it just ROLLS before settling back down.
