Depends on which lake you are on. The fish at Reelfoot Lake are being caught mostly by guys that are jigging stumps with one rod. The water is extremely low there so that is the prefered method for catching larger fish. Other bodies of water such as the Tenn. River, a host of weapons(methods) are being deloyed. One of the most popular is trolling. This is only because you are fishing a large body of water with various types of underwater structure.
The short answer is yes you can use this method now. When the fish move up in the skinny water you can still use this method but longer trolling rods in 12",14", and 16" lengths are preffered becuse it gets the pole away from the trolling motor where noise becomes a big factor.
You can deploy this method at any water temp. Water temp. should be your guide to where the fish are holding at that particular time. Every lake is different so you have to do a little research to understand how that temp. affects the fish on your area lake.
