I'm old. My butt is sensitive.No need to get butthurt because I disagree with you on a couple things.
Man, must be the change in weather or something.
But my brighter light helps a little.....and little is subjective ;^)
Seriously....the Duo and it's clones are frikkin amazing for their brightness and their tiny size. When I saw the first one last year...I laughed until the lady turned it on.
I am flip flopping on the Duo clone and a SSx2 to replace my Hi-Max XML U2 helmet light.
But with the buzz about the possible Xm_l2 U2...or better...
I still have my Vista Lite dual 10w set up from 1991....like 2 birthday candles on your bars. They were awesome back then
Then I got the Nite Sun Team Issue ( which I still have )....
I guess we have real 1st world problems arguing over bike lights, right?
