Cool! Thank you both for the helpful links!

I'm thinking the U-lock with the cable should be okay for me since I will only be leaving it for a few hours at a time. We do have issues with bike theft downtown but not so much on campus (that I've heard of). I might get an extra u-lock to make myself feel better though, haha. I will look into getting some new wheels that aren't quick release because it would be a real pain in the butt to have a bike but not have any wheels on it.

Is anyone knowledgeable about whether having multiple locks on your bike draws too much attention to a new/valuable bike, possibly making it a more likely target for thieves?

My last bike was a cheap-o schwinn department store cruiser thing, and I locked it for a whole year on campus with an equally cheap walmart u-lock. Last year I was living in the dorms and often left the bike totally unattended for weeks at a time. No one every touched it until it started to warm up in the spring and I guess someone decided that they wanted my rusty clunky mess of a bike bad enough that they sawed through my tiny u-lock and took the stupid thing. So I guess I don't even know if I'm being too paranoid or not paranoid enough? haha

ETA: My college is small-mid sized in a town of about 60-80,000 depending on how you look at it. It's a very bike friendly area so that's cool, but it also means that bike theft is pretty common practice around here. I've had a few friends lose some really nice bikes in the middle of downtown while they were having dinner at a bar or something. Bike thieves suck!
