I voted other as well. I would use more than one lock. Locks with double sided tumblers are my favorite. A u lock cable combo might be the best way.
Also when you can try to lock the bike where every body can kinda see it. What I mean is if the theif has hella privacy unveiwed he may very well give it a try. I say definitely use two locks. Don't use an older style U lock use the newer one they make now. The old ones were easy to pick the lock. I hear the newer ones are much better tho.
