Stihl are win for cutting anything. If you can cut 6 inches of concrete/rock/tarmac with no trouble then a bike lock is nothing for a pro scally. The stihl 880 i use at work can cut through 6ft of solid oak without skipping a beat. You can do anything with the right tools.
You can protect to some extent against poorly equipped opportunists(ie using all the advice/techniques/approved locks as explained on this fine forum), insure and hope for the best. Not a whole lot more you can do.
