As a start use braid for a soft bottom and weed and stiffer materials for firmer clearer bottoms however braid is also good on firmer bottoms. All rigs tied correctly and presented properly will increase your chances. you can have the best rig in the world but if you leave it to short and plug it in silt the bait will not be easy for the fish to find.
Which ever you use i would suggest you make sure it sinks to the bottom by adding putty to it. once a braided hooklink is wet you can run it through your fingers to remove any air trapped in it.
I have caught using stiff and braid types and also braid and mono hairs. I like coated hooklinks because they are more versitile.
