Long answer: Most Krypto's stink. I wrote a lot about locks (which ones are best, i have been researching this topic for years) check out my post in the thread entitled 'Your Brand new Kryptonite..."
Short Answer:
ABUS Steel-O-Chain 810 AND a Axa SL -7 or even better the AXA Defender

Never use the Axa as your only lock unless your bike is in constant view.
The Abus can be used stand alone, but i like having the Axa as back up when the hood is bad or i am leaving the folder for long.
