Do you guys see it beneficial to buy 2 Kryptu U-Locks that are keyed the same (1 key for both locks), so I can lock the frame/front wheel up to a post/whatever (Krypto Evo Mini LS), and the rear wheel to the frame (Krypto Evo Mini)?

I know you can carry a cable, but I figure that if I'm going to carry a cable around that can be quickly cut, I may as well carry a Krypto Evo Mini to lock my rear wheel up... thoughts?
