When riding Frankenbikefenderbeast I use a fat Brinks 6 ft. cable secured with a Kryptonite U lock which I store at work and can also keep an eye on my bike from where I usually work.
When I ride my road bike it sits right next to me while I work so if anyone gets within a foot of it I can bark at them.

When out an about lugging enough lock to deter most thief's is a real pain.
I suspect there is an extra warm corner of hell for bike thieves.
