Sturza,

Are you talking about the small red plastic ones that you weave your line through or the thread type that you pull tight on your line?
I use the thread type because it passes through the guides easier. As Flickyourjig stated, 20 LB Dacron tied as a nail knot does a great job. Get a spool of Dacron and you'll never need to buy bobber stops again!!

Good Luck!!
