The 1/4" chain and 340 lock is for travelling about where I might go in and eat a meal, or to the grocery store, or anything that might take less than an hour or so. If I were going to leave the bike in the same place (at work) or outside my house somewhere for 8+ hours, I'd leave a heavier lock set at both places. I would probably go with the 1/2" chain and the Abloy heavy duty lock. Fortunately, I have the luxury of keeping my bike in the house - where it is still locked up at night. At work, I'd lock up the bike with the carry set of lock and chain, go into work, return to lockup the bike with the heavier set and carry the lighter set back in. Does this take a little extra time? Yea...so what? I might return to find my bike smashed to pieces, but -they- won't get my bike!
