I've bought and thrown a flock of different nets. My advice: go ahead and get an 8' radius, 1 1/2 lb per foot. It takes a while in the back yard to learn, there are videos to teach you and they are good. You will wind up casting a small net all day, a big net a couple of times. The net I use most is an 8' with 3/8 inch mesh. This is great for most shad and circumstances. There are times that you will find the very small threadfins and they will drive you wild because they get gilled in a 3/8 in net and it looks like a silver christmas tree and you have to pick them out by hand and kill a lot of them. For those times I use a 1/4 inch mesh, which is also ok in shallow water because it doesn't need to sink fast. Good luck and be sure to PRACTICE in the back yard, it's so much easier than learning in the boat or on the bank!
