I was mildly surprised by the number of LPL fans on the other thread. Anyway, he announced what his own, personal choice was for a bicycle lock:
It's not a bad choice, not at all, and the reasons he gives are sound, but 1) with 10mm links, it's susceptible to cropping by big bolt cutters (a near infinitely more common bike theft method than lock picking) and 2) this lock weighs over six and a half pounds. A similarly retail-priced OnGuard Brute u-lock would provide higher security and weigh less. You pay your money; you make your choice.
These locks retail for ~$75, and he says his bicycle didn't cost any more than that (!). Note: It would probably cost you a couple of thousand to replicate the custom designed and fabricated disc detainer lock pick he uses to hack it.
