The smaller casting spoons can be very effective for white bass when the bite is going strong. At times, white bass will be extremely aggressive and when you find them feeding heavily on a school of bait fish, a well-placed spoon will get a lot of bites.
Jigging spoons work great for white bass. When white bass go deep, a small jigging spoon fished vertically is a great way to fish for them. A hard jigging motion will work well and most of your bites are going to come on the pause.
