depending if you are rock fishing , surfcasting or boat fishing, if rock fishing dont bother with sinker, actually any style dont bother.re braid i use braid with all styles and use at least 20m of heavy mono trace.With surf casting you can get the swivels for live baiting fom the shore(non return clips i think) which are great for getting kahawai out through the surf.Off the boat or kayak or rocks i just hook up the livie with a balloon ,Braid is great for extra strength and you know you can give it a bit more grunt.Make sure you have at least 80lb leader for the livie, dont attach it to the braid.
I use 50lb cortland blackspot on my tld25, 10lb on my softbait , and i cheat with my shimano long cast big bait runner with 50lb cortland(just in case a big ray , kingie or bronzie pops up)
If im wrong im sure some one will comment.
