I am thinking of ordering an LE. The thing I'd want from the little holster, I think, is for the light to fit in lamp-first. I don't care at all about scratches on the body of a flashlight, and worry even less about HA. But with an open LED/reflector, I do worry about scratches there. If the sheath would cover the LED and reflector, I'd be sold.
Note that kydex is a soft material, so kydex itself will not scratch your Arc AAA or Arc LE. However, since kydex is soft, sometimes little particles can get inside it and embed a bit. When that happens, the particle can scratch the finish of something like an Arc AAA, unless you keep it a little clean in there. I don't think there are any worries with the LE, although as I said, I don't care about scratches either way.

PS The relationship between candlepowerforums and Arc is amusing. I can't imagine casually asking another manufacturer, "hey, could you ship so-and-so a free one?", much less being so certain that the manufacturer would jump at doing so. Good stuff!
