(1) Your links still don't work.

(2) You entered this in a touring forum, and weight is important in touring. Many touring cyclists will sacrifice some amount of security for weight. Most touring cyclists are not locking their bike up overnight in Times Square--more likely they are locking it up while watching a movie in Leoti, Kansas. I would appreciate any advice you might have on a the best lightweight locking system. About 8 ounces is my limit.
