I keep all of mine in a standard mid grade or ultra edge mid grade, the light shines brightly through those. I've never used a Heavy blade but it's my understanding that they are a bit dimmer. Nice review (oddly it would only play once then I kept getting error messages from it afterward, but that could just be my computer.) As a fellow reviewer the only thing I would say your review needs is a part that has a close up of the saber so people can see it in more detail. You explanations about the blade, hilt, and sound board were fantastic.
Here is an example of how I do mine, the first half is up close and for the second I show how the saber looks in-hand at a distance.
