There are times that live bait is better. There are times when trolling is better. It just depends if you have a good idea of where the fish are and their movements. Trolling artificial baits will help you cover more ground. Live bait is more natural and will catch more and better quality fish at times.
If water is being let out of the dam any good hump or long point is a good place to live bait. Even "cut bait" is good in similar conditions. You want to be a couple feet off the bottom or on the bottom with cut bait. Usually one particular are of the hump will get more traffic than others. Use your depth finder to see which area does.
Free lining flats can work well with live bait or slow trolling live bait on flats.
Slow trolling with planer boards in shallow areas early morning is a good tactic. Especially when there are a few warm days with warm nights in the winter. Which we are about to experience in the coming days.
For the the guides that work HR, I'm not going to give out areas. They've put in the work to know the lake. Which is what really make much of the difference in catching fish or not catching fish. Maynard did an article for Carolina Sportsman a few years ago that covered some of the good Striper areas. I've seen it before on their website. Not sure if its still there or not but its a good read.
Having said all that....
It is difficult to catch stripers in HR after the water temp gets into the mid 40s and below with any method. Some of the threadfin shad are dying off and making it "easy pickings" for all the game fish in the lake. You can tell when this starts happening because the shad will move out of the creeks into the main body of the lake in large masses. If you've ever seen it, you know what I'm talking about. Hundreds of yards of shad tight together trying to find warmeth somewhere in the lake.
You can sometimes bounce a jig below the balls and pick up fish but there is dying bait everywhere.
Just my penny. Hope it helps.
