I use 2.5 pound nuts out of the oil field and let them set on the bottom. no so heavy it holds the jug when it has a fish but good enough that it doesnt allow the jugs to float freely all over the lake. If someone is watching the jugs and staying in the area, letting them float around works well. I dont like to stick around long after I set them. I have a LOT of success using jug lines. now is the time to get the supplies if your gonna use swimming noodles. wont be long and they will be taking them off the shelf and will be hard to find. I usually buy 20 and that will make 60 jug lines for me.
