Well, with the Michigan race coming up I made the leap to a Peter White Schmidt Wheel for light at night. That eliminates one excuse for not going fast at night, plus with the cost, I better do some good miles.
I saw a rider using this combination in Texas last year and the amount of light was unbelievable. Plus, it was easy to switch over from his day wheel to the night wheel, only taking a minute or two. The hub weighs more than a standard hub, but less than the batteries I would need with a 6 volt system. Until now I have just used some dual LED white lights but this should be a significant improvement.
