Ok, I've read lots of people mentioning balancing spinners. I looked at my spinner and then looked at my magnetic prop balancer and thought How????? Whats the best way to balance a spinner?

Unless you fly extreme speed planes, balancing a spinner (Or prop for that matter) is unnecessary

Some Folks (including myself) balance props, spinners and backplates on
all their planes. If vibration can be kept to a minimum, it helps in other
areas as well....including fuel foaming, and radio problems. Here's how to
do it with a regular balancing stand.
