Hey guys, I'm 18 and just started lock picking a couple weeks ago. I have some sparrows picks, and can rake padlocks and other easy locks open with ease. However, I want to start learning to SPP so I can actually take on harder locks. My question is: Is a Masterlock (number 3 for example) a good lock to start practicing single pin picking on? I ask because I know they have bad tolerances and can be hard to single pin pick...or should I actually get a higher end lock to practice on? I've been trying to SPP my Number 3 for a couple days with no result...thanks for the help.
