I use a standard carolina rig, years ago I stoped using a bead to protect my knot from the sinker, with great results. I always thought a bead was a must with the sinker hitting the knot. But for me anyway, the soft lead of a sinker does not hurt my knot at all, I think the hard edges of a bead can actually sometime damage your line, even if the bead goes over your knot, sometimes it catches.. I inspect my knot alot and have never found any damage from the sinker. Your thoughts?
