Looking to purchase a new lock, as I just got a new bike. Does anyone have any idea if the NY Fahgettaboudit 1410 chain (Kryptonite rating = 12) is really better than the NY Evolution 1210 chain (Kryptonite rating = 10). I would assume that the NYFU weighs a little more, but every website seems to show a slightly different weight. Also, looks like the NYFU has a slightly bigger opening in the lock portion, which may allow easier access for tools, but a thicker shackle and links. What do you think? Are the chains at good as the u-locks if you have to pick one or another? Worth the extra $$$ and weight? I'll prob use either in conjunction w/ one of the mini u locks if I'm leaving it locked for a while anyway...

Cant compare products . your dealer and the manufacturer have that data.

Hardened, thru hardened heat treated steel, steel links which use a square steel to make the links from are a good sign,
Bolt cutters will not grab the edges of square steel as well as the round stuff because then they get ahold of the center ..

A carbide disc in a power saw will cut any steel,but toothed blades are softer than hardened tempered steel

Locked bikes have had everything attached to them removed , so where you park matters, a Lot.

Worth the extra $$$ and weight? - probably not. Leaving an expensive bike in NY is asking for it to be stolen in the street or from wherever you live. No lock can resist power tools, and now power tools are battery operated. So you might as well give up on the idea of chaining an expensive bike to a pole and leaving it unattended for long periods of time. See the piles of posts for security ideas.
