I found an old cast iron pan at a second hand store that was antique (i.e. ground smooth). After cooking on the old one, I went out and bought some flap disks to stick on a drill and polish my modern lodge. It does work better. But not as good for eggs as carbon steel (which you also season, and has same durability advantages as cast iron)
