The video I saw from him recommended the Kryptonite Evolution 4 chain lock (was there a different one?). It's still quite a beast of a lock with a 10mm chain and weighs over 6lbs (standard size, the mini is lighter). Maybe not the strongest bicycle lock in existence, but still leaps and bounds ahead of many of the lower-end ones...
