dont do it all you catch is 11/2&2lb crappie.Put them out along side creek channels,rope needs to be dark,about 12'long, when you tie it around stump,tree,whatever,it makes the brush hang about 10'deep. Most of the time the biters will be on top. just try to hang the top of tree at 10or12 feet. I cut the top off flat. been doing this for years,catch 3 or 4 and move on,your tops will always have good fish, and not so many unwanted guess lol. the more you have the better. about 30yds apart, at least.I have found that if you put them closer they want hold as many fish.Good luck.
