10 Wheels: the beam pattern for that Cree looks lousy, very spotty. Can you see the road for a ways ahead (say, 50 feet) and still see the ground a few feet in front of the wheel? Also, how's runtime on low? One comment says that there's not that much difference between high and low. I like to have a 50% and about a 20% mode, since I can ride at 50% most of the time (except when doing downhills on gravel with potholes) and 20% is more than enough for most handheld flashlight use.
