I'm going to pick up a Petzl Myo XP today primarily for use on extended Brevets (300, 400, 600 & 1200K). Just wondering if anyone has one for commute use, and how they rigged it-helmet vs some type of handlebar/bike attachment.

-I had initially wanted to use my cateye microhalogen (5W,6V), overvolted with Li-Ion rechargeables, but spare bulbs are required for events (as they should be), and I simply cannot locate ANY spares. Cateye doese not carry them any more (they have the common 2.4W). Altering common bayonet type bulbs to fit (as folks suggested in the total geekiness thread) does not work either. This is still a great setup for my commute, untill I burn out the current bulb.
