I'm interested in being able to keep my bike at almost any cost. I've looked around a bit at different options and it seems to me that a combination of deterrents is the best strategy. Other than the costs, what do you think about these ideas;

Kryptonite New York Mini Lock
Spybike seat post GPS
Atomic 22 bolt system
using an engraver to carve my email address into each part.
Using a heavy duty Loctite to make it more difficult and time consuming to remove bolts

Is a Kryptonite New York Mini lock large enough to lock to things in most situations? Do you know someone who has actually collected on the insurance policy? I have a medium sized no name brand U lock now but I'd spend the cash to make sure I have a ride home if it's worth it and if they'll actually pay out.

Spybike seatpost website doesn't look very professional but if it works it would be a great way to track down a stolen bike. It only works when the bike is moving. At $155 it isn't outrageously expensive. Have you any experience with Spybike or other GPS that can be hidden in the seatpost?

Atomic 22 is really expensive, I'm talking $500 to outfit an entire bike! The idea is that a thief can't steal components and in particular wouldn't be able to remove the Spybike GPS inside the seat tube, meaning I'd catch him eventually. I love the idea of the locking skewer to eliminate the hassle of carrying a second lock. There's Pitlock too but they offer far fewer options and don't have the capability of locking my quill stem, a shame because Pitlock is far cheaper. Do you have experience with Atomic 22? Do you think it deters thieves?

Can I safely carve my email address into my steel frame and aluminum parts without weakening them? It seems like a silly question but I just don't know. My Dad carves his driver license number into everything and it has paid off many times resulting in arrests.

Lastly Loctite makes stuff that makes heavy duty stuff that makes it a pain to remove bolts and sometimes requires heat. That would slow 'em down but also make things very inconvenient for me.

Again, I'm hoping to attack the thievery problem from all sides to persuade the thief to move on. What do you think of this approach?
