When locking a bike the 50lb rule needs to be observed. If you ride a 35lb bike you need 15lbs of locks. If you ride a 15lb bike you need 35lbs of locks. Either way you are lugging 50lbs around.
I actually use an Abus chain and Abloy lock to a stainless fin box device I made to lock up my surfboards to my car. So you can only imagine the mix of chain, U-locks, etc. I use for my bikes.
But I use cables in my garage, right next to my power tools.
I will sometimes use a cable and U-lock in low crime areas where I can see the bike. But it depends on the bike.
In retrospect I remember how secure I felt with my Kryptonite tubular pin tumbler...
