Welcome from Central Florida.
I lived in TN until August of last year and shot docks a lot on Weiss and other lakes in the Middle Tennessee. Most of the water I fished had some color and though clear, was not gin clear. I can say that not all docks will hold fish and there are some days that the technique is difficult at best. It's just another tool in the box. The best I can tell you is to just keep at it and you will figure it out on the water you fish. Shade is key and lack of activity helps even more. Deeper water and suspending fish make this a real challenge, making a countdown a must. When you finally do get the day when you boat fish after fish, it's a thrill like no other. I have seen fish over 2lbs caught this way, and had a guest get a 5 1/2 lb LMB on a 4lb setup and a Bobby Garland Body. Patience and time on the water will reward you one day.
