As far as batteries go, I'm not about to buy another camera, and that takes AA. I just bought a new front light (much brighter than my old one) that actually requires two AA batteries. The rear light uses 2 AAA's, but the lantern is carrying 4 AAA's, so I can always take from that if I run out. But the rear light has a 100+ hour battery life as compared to the two watt front light at 15 hours. If I dropped the lantern, I'd still carry two spare AAA's and the spare AA's for the front light. This may change, but for the forseeable future, this makes the most sense. I definitely see the advantage of having all your lights use the same batteries, but I really like my current lights. Maybe in the future I can track down a much brighter frontlight/head lamp that takes AAA's as well.

On the tool kit, I do agree that I need to look at getting some power links and throwing a chain tool in there. I do not however, believe I really need extra cables and spokes, etc. For one, the cables don't have that many miles on then and the RD cable is brand new. Also, the wheels are brand new, so I don't expect broken spokes. The multi tool does have open end wrenches, allen keys, spoke wrenches, and more, so it's pretty extensive for a small package. And a pedal wrench? I really don't know why I would need that at all. Enlighten me? And remember, this is only for three days and about 220 miles on a bike with freshly packed bearings, a headset with only a couple of hundred miles, and new wheels.

I do need a knife. But I always have a knife on me, so I kept forgetting to put it on the list. It will go in the handlebar bag. I'll probably just take my cheapie benchmade. It's the lightest one I have and does a good job. Good point bringing it up, though. It is a must have.
