I just implemented a Shimano Hub 3n71 solution hooking it up to 4 Luxeon 3 lights. It is plenty Bright and so far is working out well. A friend and I are running a 200k permanent starting at 10 pm Friday night just for kicks. Should be a good test of the new light. I use a Princeton Tec EOS as a backup and standlight when stopped.
As far as eating and drinking at night, usually I have been following a schedule of eating all day so it just comes naturally to me at night. I do have to watch not overconsuming fluids at night though as that slows down as the heat drops.
