Hi guys,
I recently bought a Specialized Tricross singlespeed for my college commuter. I am looking to make riding both enjoyable and convenient. I am thinking about picking up some clipless pedals to deter thieves from stealing my bike. (To complement my Kryptonite Fahgettaboudit u-lock)

Currently, I have Shimano PD-M520-L mountain pedals and Specialized mountain shoes for my Allez roadie. I want something that would potentially deter thieves due to the difficulty of riding away. My LBS recommended Crank Brothers Egg Beaters for the quality and unattractiveness to thieves. I plan on switching shoes upon arrival to class, so I'll be able to carry my bike shoes in my backpack.

Any recommendations? Thanks!
