Weinis, I think you got no answers is because everyone has their favorite size, and the size one uses to catch fish can change from day to day, even hour to hour. Let the fish tell you what they prefer, only having one size is like going for bluegills with one jig, you hope its the one they want, but most times you have to try a few different ones before you get the right one. Get yourself 2 or 3 different sizes and you will be good, hope you catch a bunch, Carl
