There are several types of TWs, all in use by pros. So, the type you need is the one that works best for you. Sometimes I use one, sometimes another, depending on the effect.
The lead, you are looking for is thicker than typical lead (#2 pencil). You might want to head to the art store on this. It isn't only the size, but also the legibility, etc. Some folks use "China marker" types for a good, legible, thick line. If you want more of a normal lead look, you will have several to choose from - and then you should pick up a pencil that matches your lead type.
