I have used shaky heads a lot on clear and stained water. When using shaky heads in depths down to 20' I stick with 1/8 oz. However, when going deeper than that I use 1/8 to 1/4 oz. (depending on the shape of the jig head). I make my own aspirin head jigs that fall at a fast rate, even at 1/8 oz. sizes. I also use florocarbon line in 8 and 10 lb. variaties (depending on the depth). Florocarbon will sink faster than mono.
