Thanks for the feedback on the XPL unit.
I was just playing around with mine last night, swapped on the millenium turbohead and older LF tower (XPG2). The unit I have in the stock head is a Nailbender, which has a great beam and tint. I think I should have gone for the low voltage unit to allow using a 17670 and spacer, but something bugs me about requiring a spacer such that without it I can't use the light. I need to get my hands on a few more 17500's.
