I also use tube jigs and prefer 1/8 oz but at times use 1/4. Like said before it is impossiable to hold a jig perfectly still on the end of a 11' jig pole . It move it slowly trying to hit every part of brush or condo . The fish will let you know if they want it fast or slow . Up high or low . Sometimes it will need to bump cover and other times they suspend over or near it . I too use purple / chart but use Southern Pro umbrella tubes which are fatter and use unpainted heads up inside them .
