I'm very curious on exactly how the MLS works. Do I need to order another blade holder and LED (wiring as well) or just another LED and wiring? Also, just ordered the Bane in RGB with sound. If I get a single color tri-rebel (red is that I'm going for) will it be brighter with all three dice activated or will it be the same brightness as just the red dye on the RGB?
Really, with RGB there is no need to switch colors out because the RGB will cover every color VERY well. From what I have see, the shade of red is comparable to a P4 red (but that's just me, others may disagree). But I for one was very pleasantly surprised how bright each color was on the RGB saber I saw.
My advice: Stick with that you got. Your red will be just fine.
