Because most of our mega-lakes are river fed they will have more logs and trees washed down than smaller creek fed lakes. Every lake has some local lure color or bait that is more productive than others when used on it. If you feel like a new lure will help catch fish on a lake by all means buy one. Just remember tackle dealers are there to sell lures, so use common sense when buying. No matter what locals may say, if you don't believe a bait will work you will not fish it to its full potential.
Confidence is a major player in solving the puzzle of any lake of any size.
If you have confidence in a certain lure you will keep it in the water instead of on the deck. In 30 plus years of fishing I have only had two bass jump in the boat while I was changing baits. I caught the rest when my lure was in the water. A big lake is just like a puzzle, but instead of putting it together just take it apart a section at a time. All rights reserved.
