With all the advocacy for how good the FENIX, etc. flashlights are, I wonder if they're a good option for helmet mounting.
a) does the extra weight of the batteries up on your head, rather than in a jersey pocket, get to you? I'd go for a small one, and their batteries tend to be smaller than bike-specific lights, but it will still be more weight than a lighthead only.
b) is there a handy lockblock-like thing for helmet mounting?
