The most common application is a 2 ounce weight connected to the main line with a swivel, then another swivel and 6' of mono to either a reef runner or crawler harness. The weight can also be connected with a rubber band to the main line and connected anywhere from 6' to as far as 50' ahead of the lure. You can use any amount of weight from 1 ounce to 6 ounces with the most common being between 1 and 3. Any time you use weights, speed will greatly affect the running depth of the lure and also create a lot of vertical movement in the water column as you turn and adjust speed. Hope this helps...
