I use Seaguar Invisx 6 lb. test, size 1 Gammie Drop shot hook, and a Zoom Finesse worm, I like Old Purple or Plum. Tie the hook on, point up, using a Palomar knot, leave about a 2 foot tag end to attach your weight.
That being said, you'll probably get another 10 or so suggestions on different ways to set up, but that's what works for me.
I have not done crawlers, but if you do, you'll probably be pretty busy with fish, all kinds of fish. I don't know what hook size to suggest with crawlers, or whether to use a whole one or pieces.
