I mean the components that go into the key system itself.
Currently in america, that type of double sided dimple key is among the most secure and restricted. And yes, they are almost impossible to pick, if that matters to you.
Remember:
Most thieves will not take the time to pick your bike lock, they will break or cut it.
When you see a lock using that type of flat, milled key, chances are very good that they are not easily duplicated and a lot of care has been given to defending the lock cylinder itself.
As far as the 'U' part of the lock is concerned, it seems to be pretty standard. As with any U lock, one should use the shortest length that is convenient/feasible.
