The Master lock could loop itself around something a u-lock won't reach, thread through the front wheel and lock to the Knog on the back wheel/frame. My smaller Knog won't reach around the frame and rear wheel, I just thread the cable through front wheel, big frame triangle then to Knog around rear wheel.

I would forget the first "cuff" lock that you linked to.

At some point, anything you get is better than nothing yet not good enough. You can only stop the idiots......a pro will get your bike no matter how you lock it with however many expensive as you care to get locks.

You can only use "security level" indications on lock mfg. sites, cost, weight, trouble and theft rate where you leave your bike to determine what it would take to make you a bit more confident your pride is secure.
