Until recently I have had a slip on Texoma for 25 years. Some years better than others but I've always had crappie in my freezer. Brush is the most important factor. In 26 fow I would definitely suspend a lot of brush 15' range and when you think you have too much brush put in some more. I'm going to assume you are on the eastern side of the lake and I've always been at Big Mineral. I've caught fish on a myriad of colors and types. Brown and orange, white and chartreuse, blue and chartreuse, and pink and white have always produced.
