Security Chain Talk

Hi all,

While it's in the garage I'm looking to secure my pride and joy with a hefty chain and ground anchor, and there's no shortage of options in terms of manufacturer to choose from. I want to go as big as possible to make it as hard to steal as I can, so my question is this

Who uses the thickest chain, and how do you route it through your bike?

Photos would be appreciated. If there's already a thread on this so would a link 😊

Cheers
