Thanks to Varjeal's thread on links to locks, I found one really good link on that thread. I'm posting it again in case a new member like me might have tons of question about picking method and how much torque to apply. This link is very desciptive and you can learn alot from it. I sure did, so thank you Varjeal for posting this link. To the newer members of the forum, here is the link:

It also has a neat little video. Good luck!!!
