You should reconsider your decision to get the Street Cuffs.

The NY3000 is about as good as a Ulock gets. Get one and it's unlikely that anyone will defeat it.

You can run the lock through a frame member as well as the rear whell if you like, but cutting a rear wheel is not so easy and would destroy most of the value of the bike to a thief so it's unlikely that one would go to the trouble just to get the frame.

Forget cable locks. A thief can cut them with little trouble. Instead, to protect your front wheel, either remove it and place it next to the rear wheel so the Ulock goes through both wheels, get a second Ulock, or get a security cable and padlock (Kryptonite or OnGuard make good ones) The chain is heavy but if you are locking up to the same place everyday, you can leave the chain locked p and not carry it around.
