I've used Slab sauce the last two years. I find it most effective early in the year when the water is cold. Early year, cold water, crappie fishing I use feather jigs. I barely move them. the water current will make the feathers "dance". Slab sauce really stays with a feathered jig. This year, I also ordered some G sauce. Can't wait to try it......Once we quit having mornings of -17 degrees
