I'm in the process of moving (ok well preparing for the one day move) to a much higher crime rate area than where I currently live. I've been following the Bic Pen holder lock threads with great interest. I think I've settled on getting the Kryptonite Chain or an Abu$ chain and lock. Does anyone have any comments on the Moly lock currently on the new York chain?
The molly lock has a long shackle that may be susceptible to bolt cutters. I would look for a padlock with a shrouded shackle that has as little exposed as possible and still work with a chain. I would worry less about pick resistance (but no tubular keys!) since few thieves are going to bother picking a lock. You want brute force protection.
Consider using two locks. One being a chain and padlock. The other a good U-lock like the NY3000. If you use both locks, a thief has to defeat them both which generally requires different tools or extreme measures like an angle grinder.
