The best option is the one you will use and carry with you. Looking at some of the weights listed for the armored cable locks, I am not sure if I would carry them.

Is your area high crime rate, and if so then what type of crime? Most thefts are crimes of opportunity. If that is the case in your area than anything you use as a deterrent should be sufficient.

If you have a roving band of bike thieves with angle grinders, bolt cutters, and whatever, then nothing is safe. It will simply take more time to get at what you have.

With me, I will sometimes use the the cable that came with the lock I bought. Have you also thought about using pitlocks or something similar?
