That's the problem I have now. My cable is a $12 Kryptonite Flex, my lock is a Master Lock Magnum. The Magnum can't be cut by hacksaw, and takes so much force with a bolt cutter that you'd break the bolt cutter. The cable ... can be cut with cable snippers.
The chain here is the same kind of material; you need an angle grinder to cut it. The lock I have is of the same stock; and the U locks I'm looking at require about 3 metric tons of force to break the locking mechanism itself, much less the shackle or the lock body. For reference, a decent floor jack supplies 1.5 tons of pressure or higher, while a bottle jack supplies considerably less. You can break a bottle jack on some of these U locks without defeating the lock itself.
Someone is more likely to saw through my frame and wheels.
