Fishing shallow water 3' with lots of color I put about 5' behind the boat with a k11. The deeper ya go and the clearer the water the more you put out. the most I've put out is about 30'. Make sure you put a bead above your barrel swivel to protect your knot. K13 is the biggest kwikfish I've used. Any bigger is too big depending how much currant is running. A magnum tadpolly works good too.
