That hub + a Lumotec Oval Plus headlight, and a B&M DToplight tail light on my commuter. It's been great, very little drag with the lights on, none when they are off. The hub also has threads for a rotor if you ever want to go with a front disk.
+1 on avoiding the Shimano headlight, in comparison to the Lumotecs, it was a toy, the hub however is a fine piece of machinery.
