Ah, very helpful replies for a first time poster, thank you.
The Kryptonite locks did come with the standard frame mounts, but I find that the U-lock rattles in it, and the mount ends up magically spinning out of place after only a day or two. Though, I have seen a few links on the forum for custom U-lock mounts, bags, pouches, etc. so there's another option for down the road (no pun intended, huzzah!).
Bear in mind that every electrician in the business has cutters on the truck for cable much heavier than the Hardwire.
THIS is exactly the info I was looking for. This is what I was worried about, as I know that the people who are hardcore into stealing bikes have a disturbingly prepared setup, with the professional tools, and the pickup truck they throw the bike into in 10 seconds. Jerks. I will likely stick with the U-lock, and try shoving it in my Chrome bag again. (I've been skipping the two-lock method because my wheels are bolted, not quick release.)
Thanks again.
