I don't have any high end bikes but I also use a Abus disc lock with a cable, never had my bikes ever stolen, but I also live in a low crime rate for bikes, the lock is bullet proof, it's somewhere around 40 years old and still works like it did when it was new. Anyway, realize that any lock today no matter how much you spend for it can be defeated in less than 2 minutes with an average of 45 seconds, if you use two locks you may buy yourself as much as 4 minutes at the absolute longest. If you live in a high crime area for stolen bikes then I'm not sure why you would trust locking a highend bike up someplace while your away from it for a while, I would buy a used bike for cheap and lock it up with a cheap $45 lock. But that's just me.
