Do you think the kryptonite mini 7 or mini 5 is better? I was reading that smaller is better in terms of having less maneuvering space for the thief. This combo doesn't seem like a bad deal. http://www.amazon.com/Kryptonite-Mini-7-4-Foot-Flex-Lock/dp/B004C94T84
In the city, I run a Kryptonite Evolution Mini Bike U-Lock through my frame and front tire, along with a cable that runs through my back wheel.
In the college town I live in now I just use the U-Lock.
