Cool, nice setup for a "beater" bike. those Twofish mounts really allow for a quick and clean install. I just ordered an xm-l zoomie (2x18650) from ebay; hoping mine won't "auto-zoom" either when hitting bumps on the bike. Lots of mounting options...I almost got the Twofish mount but I wanted to experiment and try this one: http://www.tmart.com/Flexible-Rotati...k_p120110.html we'll see...i'll post some pics and a mini review when I get everything put together and on the bike.
