This technique kicks up small puffs of sediment, much like a crawfish on the move. A very slow, steady retrieve is another technique, especially in cold water when fish are lethargic. Finally, try several consecutive very short jerks, then let the lure stop for a few seconds before repeating the action. As for the pig part, use an opposing dark color pork rind, plastic grub or imitation crawfish. The weight of the jig used is a matter of personal preference.
Some anglers say the deeper the water, the heavier the jig.
Often this is a mistake. It is only critical to feel what the jig is doing, regardless of water depth. Once the water reaches the seventies it s time to start tossing them. Work them in the morning and evening on clear days. With over cast skies they can be effective all day long.
