So I've saving up to build a new commuter when I get home from school in a few weeks and need to decide how I'm going to make my new bike move. It'll be primarily a commuter with potential loaded touring and fitness cycling capabilities.

Key highlights include:
1. Surly Cross Check
2. Cetma Rack
3. Dyno hub + 2x Lights
4. Fatty tires (with fender option - a pair of full wooden Fast Boy Fenders would be nice)
5. V-Brakes (for simplicity and ease of maintenance)

Initially I was thinking of a Shimano Nexus 8-Speed (premium model) would be fun but I've recently begun to look at cobbling together a Campy Centaur centered drive train.

Any suggestions are welcome. Mainly I just need to have someone else's ideas to mull over because I know I'm missing something.
