1. Main line flouro (as light as you can get away with, provides for better action, or lack there of, to your bait) (Sunline SniperFC is the best i have used by a long shot)
2. a small steelhead swivel for general use, 2 or 3 feet above your bait, is not required, but will save your expensive flouro from MASSIVE twist issues.
3. a palomar knot to connect your hook with the tag end fed back through the eye towards your weight provides a nice 90 degree angle for the hook.
4. attach your weight to the bottom.
NOTES:
- you can play with different baits, hooks, and hooking sytle (nose hook, texas rig, threaded, etc...) depending on targeted species and conditions (open water, weeds, rocks, current, etc...)
- quick release weights are nice and easy to attach and move, but they do nick the line. if you can find ones that tie on they are better.
- round and pencil style weights are better in different situations. i prefer pencil style 90% of the time. don't waste your money on tungston for this application.
- play with the length of lead between your weight and your bait. keep in mind that if you are casting / dragging the rig that you will require a greater length of lead to achieve the right height your bait runs from the bottom.
- when ever possible try to fish the rig on a "semi-slack" line, and not a tight line. this allows your bait to sit seductively still with only slight current and movement required to provide life like action. if you know you are in the strike zone try to leave it dead still.
- watch your line, and have your finger on the line. some of the biggest fish will hit with the slightest tick.
- don't go for bone crushing hook sets. rather try sweeping hooksets across your body. this can move the bait 12 feet or more in one motion and with the light wire hooks i generally use they provide for very positive hook ups.
- if you are not getting bit, but are marking the fish and know they are there, keep changing up the baits, often this is key.
hope that helps. happy to answer any questions beyond this info.
