if you ever wander down the road a bit to las vegas, we fly at night every friday at the new silverbowl park. we do have many thousands of watts of light to fly by but you're welcome to wear your headlamp, in a belt and suspenders sort of way. we love having visitors, blindingly cycloptic or not.
it sounds like you're squared away but for others who may be reading, there are some very
bright lights with cree emitters built for use on bicycles these days which could be worn as headlamps which would have no trouble at all lighting a kite at 100'. check out the magicshine brand if you're in the market.
as for the quality of the wind; for us, if the wind hangs around after the sun goes down, it does appear to be much smoother. it's still up and down in terms of strength, but with fewer bumps and ripples, if you will.
