SBGobbler, I wasn't saying that the lumenok caused it, but he was shooting into a field and claimed the arrow "blew up" in mid flight. Nothing left but a bunch of carbon splinters.

I seem to have no problem following arrows from my Switchback with white vanes, but everyone is different.

The most important thing is confidence in your equipment, and don't change it if it ain't broken.

Again I have never used lumenok's on any of my arrows, so I can't really say if they have any disadvantages. I was just saying from what this hunter had told me.
