Best Lock to Buy?

kboy ah, a post i wanted to write but didn´t dare! Think the other posts are quite messy and doesn´t really come to a conclusion.

My plan is to use a few different locks so it would need more than one kind of tool to nick my bike. I´m thinking d-lock for frame + back wheel to post, then maybe a chain / cable / steel-o-flex for front wheel + frame to post. Or maybe just get two d-locks?

what about these kind of locks, are they any good at all?

also heard rumors about a lock that comes with an insurance, is that true?

That's the Abus one I've got. Goes round your waist a treat and you don't even notice you've got it on. Mini d-lock in your back pocket/waist band and you're set. Or pitlocks and one lock.

This isn't a conclusion, by the way, just what works for me - I'm sure there'll be people who think that's the stupidest combination ever...
