My personal preference are the slimlines. I don't have a problem with bending my picks all that much, so this is a good choice for me. If you are rough with your picks, you might just want to go with the standard ones though, at least for your first set. The only problem with that is, you might start running into situations where your picks may feel a bit bulky inside of the lock. So, if you think you're pretty gentle with your picks, I would definitely say slimlines are where it's at.
As far as what picks.....eh....that's really personal preference. I'm sure you're going to get a bunch of different answers, but here's mine.
A half diamond,
shallow feeler,
deep feeler (and maybe one in between),
and maybe a camel back or sawtooth for raking (preferably camel back though).
Those should get you by with the majority of the locks you'll be practicing on. By the time you get to locks that need other picks than these, you'll know what you need
I would probably invest a little more money in tension wrenches. See if you can get a couple different sizes. A lot of times you can use different picks on the same lock and still get it open. But, if you don't have the right tension wrench, you're going to catch hell trying to keep that thing in the right position.
Hope this helps
