The only time I use a weight with a spoon is when I am straight line trolling. I agree with "Pegsguy" on casting. If you are using a small spoon then you will need to use a lighter line and perhaps a lighter action rod. What I am saying is if you are trying to cast a 1/8 oz spoon (or even 1/2 oz some times) or lighter you will NOT have good luck with 10# test line! I use 10# and up for 3/4 oz & 1 oz spoons. I hope this helps!
