What's a good intermediate-beginer lock with security pins

[AlexMHH]

I'm just beginning to be able to consistently pick a few of my locks with security pins, but I find myself at an impasse: I have no problem with an older Ace hardware brand brass padalock and my A bus Diskus 24/50, but the several newer Ace locks, Brinks Shrouded, American 5200, and "Phillips 6/Assa Abloy" 4 pin mexican padlock all have me blown away. Are there any suguestions for moderately easy locks I can use as stepping stones to these others?

You should get your hands on a schlage b360 deadbolt. It should have spooled security pins. It can be rekeyed, and you can take out all but one or two pins if you like. Also it doesn't have those nasty serrated pins that are in the american 5200.
