Pitlock vs. Pinhead

[PamNY]

I'm going to get wheel and seatpost locking devices for my new bike. Any opinions on Pinhead (which I have now) vs. Pitlock? Or are there others I should consider?

Also, any ideas on securing saddle with something other than a cable? There should be something that requires more than an Allen wrench to remove the saddle, but I can't find it.

Also, has anyone used the trick of supergluing a ball bearing in the Allen bolt recesses? The saddle isn't something you remove very often, so it's tempting. I just want to be sure you can clean it out if you need to.
