My favorate rig... You first just feed your line though one side of a small swivel, then feed on a small plastic bead, then tie on your hook. I use 8/0 gammagatsu octapus. After you tie the hook on I use a lighter diameter mono to tie the weight to the swivel. I leave about 10-16" of light line usually 12# test. What this seems to do for me is use smaller weghts in the current cause the tab of line gets down in the rocks. It also slips easily though the swivel and allows the fish to run without feeling the tension. This rigs has really upped my hooking percentage. I tend to stay away from a leader cause I fear of breaking the short piece of line during the strike.
