Major (or Kate for that matter), if you do fancy an Led Lenser H7r, I've got one, new and unused and simply gathering dust (literally - I left it sitting on a shelf for a long time!).
I first had an H7r and did really like it but after a few used the charging failed so I returned it for a refund, and looking around for alternatives I settled on Zebralight, first the HS51 and this year I've succumbed to the new HS52. These are very bright and run on a single AA. The HS51 had a max 200 lumens, and the HS52 puts out 300 (similar to my Exposure Joystick bike light). The burn time isn't all that long if you use maximum output all the time (around 1hr) but you can set (configurable) lower outputs, plus a spare AA is easy to carry (and I like the way that you're not forced to use 3 or 4 of them just to get the torch to work).
Anyway, a year or so ago, probably after a discussion on here, I decided I quite fancied another H7r and found one, but in fact I've stuck with the HS51 / HS52 and never used it yet, so realistically I think I'd part with it to a good home.
ExOfficio Briefs work pretty well... although I actually prefer the longer length Boxer Briefs for walking, even in warm weather, as I find the length helps avoid unpleasant chaffing where you really don't want it when the going gets sweaty!
