I use a Kryptonite New York Lock - not the Fahgeddabout it, but the bigger version designed for 'Powersports', the M-18-WL. It weighs a ton, but I tend to leave it where I lock the bike during the week and take it home at the weekend. It has an 18mm thick bar and says "You might want to consider trying to steal some other cycle nearby" to anyone who cares to listen. Add to that the lightweight Abus Granit Futura I have clipped to my frame, and a Kryptoflex cable to keep the wheels safe. I also have a spare Abus shielded cable that I use when I have left the NY Lock outside work. The chains look the business, but I was put off them when someone posted a video of some guys with a bolt cutter making short work of pretty much all of them on this very forum.
The top of the range Abus square section D locks that d0cA recommends also look pretty good, and they're probably lighter than the NY lock, but they don't look quite as scary.
Totally agree with bobby on the lock-oiling issue, particularly if the weather ain't so good.
