I am also very new to this, but I like using the small pointed tip to do lettering. Also not sure what kind of wood you are using, but so far I've had some good fortune with basswood. There is little to no grain so your pen tip doesn't "jump" when you're going perpendicular to the grain, and it responds to heat very well.
Here are the basswood pieces I got on Amazon - Link
