Best Lock to Buy?

that is my locking rig..

the abus granit x plus is well respected, but weighs literally a ton.
i dont mind so much since the extra weight keep me fitter, but it might put a lot of others off.

Abus Granit-X plus D-lock through frame and back wheel and cable lock upfront is the way to go if you ask me. I couldn't find anything on google about breaking one of them...

The good Kryptonites are probably just as good too.

I wouldn't use a cable lock as my main lock, I don't think any cable lock would stand up to a pair of bolt-cutters for long.

Nothing with a barrel lock, nothing with a combination lock, and don't leave any room in your d-lock for a car-jack or whatever. Probably the best you can do really.
