No problem. I assume you know you can't drop those american padlock pins in your practice deadbolt. In general you shouldn't mix padlock pins into deadbolt sized cylinders unless you know them to be the same diameter. You can usually tell at a glance, but it doesn't hurt to google before you start mixing pieces.
Check out that link squelchtone posted, then his link in the other thread about this same topic. Those LAB spools are cooler than the one's in the schlage, weiser, or any other random kit I've seen. I'd imagine a bit harder, and cheap too. Very cool. I don't know how I missed it in that other thread. Thanks Squelchtone!

The only barrel pins I've heard about are in the new master anti bump line. Other than that I don't know if any other company uses them. They're not exactly the toughest to pick.
