Among all the thefts I have heard of or experienced, I have never heard of a dedicated bike thief actually picking a lock. Even the old, openable with a bic pen, ones always seem to be in pieces on the ground.
It’s far more likely that the attack is going to involve an angle grinder or big ass cutting tool. Here in Vancouver people get spotted with massive bolt cutters or angle grinders at a disturbingly high frequency and don’t seem too concerned about witnesses to the theft. I go with the policy that the larger lock is a better deterrent as it takes longer to get through. Nothing will stop someone with determination and sufficient time.
