I would like to come up with a sink tip rig to fish for white bass on the Cumberland River below Cheatham Dam. Typically, my father and I spin fish throwing a 1/4 oz jig/sassy shad to the bank bouncing it slowly along the bottom (4-8ft deep) while drifting down stream. We are usually casting inside of 40ft or so and the water is fairly swift. The trick seems to be a slow reteive near the bottom. This spring I want to try my 8wt, but I'm not familiar with sink tips. I need something to drop a fly as fast as a 1/4oz jig would in about 8ft of water. Any recommendations? Thanks!
