well, during the winter there is a group that rides dirt roads that i road with in the fall, and would like to start back up to get my legs under me after my cast comes off in the next couple weeks. I road it with my blackburn voyager 3.3... NOT enough light... most others are using helmet lights, some from light and motion (stella?). These seem to have quite the premium pricetag to go with them. I have been looking for a good light around $100, and PB has a sale today (cyber monday apparently), and i think it was something like $20 off of 100, which peaked my interest again today
