Onguard makes mini-LS versions of their high-end locks, though they don't seem to advertise them, and I had to special order. I just don't LIKE them as much as I like the Kryptos, mainly because of the design of the bracket meant to mount them on the bike. Check out the Brute Mini LS, http://www.bicyclebuys.com/Items01.a...T=118&P=1&D=NP - which seems VERY strong, but which weighs nearly as much as a Krypto New York chain, at nearly 7 pounds.
