Im thinking about getting a Heavy Duckett Ghost for jigs and Texas rigged craws, what type of line should I use?

I'm a fan of braid with a fluoro leader. If you are fishing a lot of deep water, get some sinking braid.

I use fluoro for those applications, 12-20 lb depending on the situation.

Id say braid.

Seagur red label 15lb is what I use but any type of flouro around that lb test will work.

I'd use fluorocarbon.
