I started Pushing with egg sinkers .... I just put them on the main line & put a bead with a big hole on behind it , then tied on a duolock clip. Then all I had to do is make up some 3-5ft leaders with a loop knot to go in the main line clip and a clip or swivel on the other end for the crank.
I used the big hole bead to keep the egg/barrel sinker from rubbing on the knot at the clip.

I don't use egg sinkers anymore. I switched to trolling sinkers (torpedo shaped) .... 1oz for jigs & 2oz for cranks.
