I have a new bike, and I'm just a bit paranoid and really really don't want it stolen.
I already have one D-lock which was fine for my old banger of a bike, but is not going to cut it with this new bike.
I'm thinking I should really spend the money on a good kryptonite D-lock, then use that plus my other D-lock and a cable as well, should that be enough?
And what about the sea? Will it be ok or should I get another cable to go through that too?
DS had his seat nicked off his bike, and it was a rubbish cheapo 6 year old's bike! 
I just want other people's advice and experiences really.
How can we make sure our bikes are safe from theives when we have to park them outside in public?
