How I deal with them is to watch the lake the day before I want to fish and see where the spider rigging/cranking crowd is. Before daylight on the day I want to fish, I string several unmarked trot lines about 3ft deep in the area my competition was fishing the day before. This usually keeps them busy until I can catch a limit and get gone. I have found that trot lines made out of yarn really tangle up good and are quite inexpensive. No hooks needed.
