I agree with Champ that being a guide is stressful and you are expected to have a successful day regardless of the variables. I've hired guides in the past and will do so again in the future but the success is not based upon the size or quantity of the fish caught. Rather I hire a guide to pick his brain about the particular lake, conditions, lures, seasons, etc of the lake. I hire them for their knowledge. I evaluate his knowledge based upon the guide practicing what he is telling me. I hired a guide in FL on Lake O a number of years ago and all he talked about was catching fish on 12" black worms. All we did all day was fish with large shiners under a balloon bobber. My advice is look upon a guide trip as a learning experience rather than a fishing trip. Ask all the questions you have about the lake. Take what you learn and put that into practice on your future fishing trips. The end result will be a great experience for both you and the guide. IMO
