I decided to use some lead that I had left over from years past that I utilized for duck decoys. I knew one day the lead would come in handy - glad I kept it. I chose the following weight sizes: 1. 6 oz No Roll (Qty 3) 2. 6 oz No Roll Bank (Qty 7) 3. 8 oz No Roll (Qty 5) 4. 8 oz No Roll Bank (Qty 17) 5. 16 oz Bank (Qty 13) I am curious to know if this range of sinkers will cover me for the Mississippi and Missouri Rivers? Do you think I'll need a 20 oz, or 10 oz?
