As far as braided line goes-If you're dragging 20lb balls use 250lb or suffer the losses. Be sure if you're using swivels that they fit through the pulley on your DR. Tuna cord. para cord, halibut ganion, heavy tarred mending twine, and many other types of twine will suffice depending on what you have on hand will work for cannon ball connections. Having a good set of crimpers is an asset if you want a nice tidy looking set up.
Basically, run what you're comfortable with, what you can afford, and in most cases what you have on hand will work saving you even more money.
