It's best to avoid the tiny pointy tips. A medium screwdriver tip or a horseshoe tip (conical shape with a flat section at the end) works best. The reason is you want a good contact area to conduct heat from the tip to the job. Tiny, pointy soldering tips are bad at this. You will end up holding the iron in place for longer while waiting for the joint to get hot enough, the flux will dry up and stop working, and the parts may be damaged. The ideal solder joint is completed in 1 or 2 seconds.
