The best way I've found to make a symmetrical bead is to use a thicker stringer (~2-3mm) to lay a footprint on the mandrel, and then go back in carefully with your regular rod to add more glass. Once you get some more practice you'll be able to use a regular rod to lay a small footprint and then beef it up more.
