Bass Pro Shops, I know, and maybe Cabela's, sell a small rubber bobber stop on wire loops (45 for $1.79) that are much better than the string/tube kind. I have both and have found the little rubber one are much easier and more durable than the string kind. They come in sizes too, for light line/medium line. You just run a few inches of line thru the wire loop and make a small loop between your fingers and just pull the rubber stopper onto your line until it clears the tag end. Wet it with a little spit and slide it where you want it. No beads. feed thru the rod guides, last a long time.
