As an update to the thread, I've had my P7 for about a month now, and it's hands down one of the best bike-related purchases I've made. I just came home from a night ride with it (to a friend's house and back), and the greatest compliment I can give a piece of gear is that I don't have to think about it when I use it. The P7 in front is like that. I know I'm visible to cars approaching me, as well as to cars close behind me, and I can see whatever's in front of me. It's great.
