hard to say, I'd say look through forum posts to see which corps stand out, or just go do the stuff you normally do and talk to people in local, talk to your targets (or killers), fellow miners, ... whatever it is. Join those you enjoy talking to and see where it goes.
Small corps are hard if you don't know them beforehand. It's easier to find a handful of really cool people you get along with in a bigger group.
