Surf rig or the Hi Lo Rig
A proper Dropper Loop should NOT be too long or it will twist and foul during the cast
This illustration shows two dropper loops tied to a length of mono with the pyramid weight ahead of the line.
40 pound seagar flourocarbon is a good idea when the fish are finicky.
Barrel swivel on one end to the standing line and snap swivel to the pyramid.
Overall the finished leader should be a couple of feet long.
If there is any movement in the knots, they will break so use a screw driver to slightly pull and seat the knot.
Bank sinkers are more aerodynamic and less snaggy for rocks while the pyramid is a good one for a sandy bottom
