I personally don't worry too much about going overboard to lock up my bikes with various gadgets. If I use anything I use a cable and lock the bike to something solid. One thing that I will not use is a disc lock. I saw a van pull up to parked bike with a disc lock.... four guys hop out with two baseball bats... they run one bat thru the front wheel and one thru the rear. On the count of three they lifted it up and put it in the van. The bike was gone is less than 30 seconds.
