I'm not sure about the c-rig, I've never had that prob w/tungsten and glass beads. About the wooden peg vs. the plastic........ The plastic peg (which tru tungsten makes) is MUCH better. What happens with the wooden peg is that it pinches your line tightly against the sinker which will rub your line across the rough edge of the sinker causing a weak spot. With the plastic pegs, your line passes through the peg eliminating contact with the sinker itself. Hope that helps. Drew.
