Andy, I buy mine from Terminal Tackle. They are called spin-n-glo. I use the 3/4 inch pearl white. I also use chartreuse. I usually buy 100 in a bag. They are cheaper that way. You can use them with teasers.
Thanks Seabird and Steve. Those are the pics of the spin n glo's. They definitely give you a bit of an edge in murky water. I had a couple white ones but lost them to snags on the ocean reefs. Should just kept them handy for the bay.
