STRIKE ZONE, I'm pretty shure Hoh. is referring to tri-beads. They are trianlgular shaped beads with knobs on the tips of the triangle. When stacked they kind of nest together. The only place I have seen them is in the Cabelas saltwater fishing special catalog. You can order them from www.cabelas.com just type in nz-31-3970 in the catalog ordering space. Unfortunatly they don't have a picture of them on the web page.
