I use a chisel or screwdriver point on my iron. It is small enough I can get one edge on the PCB trace and the other on the component lead. You want heat into both so the solder bonds them together.
I solder more often than the instructions call for just to keep the leads out of my way while soldering.
Paul Joppa, who has soldered more than I ever will, uses a pencil tip on PCBs.
