Never really used egg sinkers until I got tired of having the same tangle problem while bottom bouncing sand eels on the CC-Canal.
I swear by braid, (mono leader), but when casting, the fishfinder rig would often wrap around the line during the cast and defeat the purpose of the slider setup. Also, those fishfinders tend to grab onto every hunk of seaweed and submerged snag it hits.
Well recently, on one particular canal outing, I seemed to be getting snagged and breaking off on almost every other cast. I was fast running out of tackle. Scrounging around the area, I managed to find several barrel swivels, a hook, and one egg sinker. Well, I tied on that egg sinker and immediately found that casting was easier, so I got more accuracy and more distance. And thereafter, I didn't snag up even once for the rest of the outing. The quality fishing time spent "in the water" increased, without wasting all that "retying time". And I then began catching fish after fish...
So later on, I stopped by M&D's and bought a bagful of 2-3 oz eggers.
One item, you should put on a plastic bead between the egg sinker and the barrel swivel/leader to keep from having the sinker wear on the knot and from crushing the swivel.
Good Luck.
