I just bought the Lumenok and have the Tracer on the way to compare. I have had a problem with the Lumenoks tiny metal contacts makeing a tiny little notch it the end of my carbon express arrows after a few shots, so that they quit working because the contacts no longer get pressed in on the shot, so I plan to put a thin light washer or hard coating (JB Weld?) on the end of the shaft to keep this from happening.
