I was wondering if anyone could tell me what nib would be roughly the width of a ball point pen. I have a 2668 now but it is a little on the toothy side. So I was looking for some help.

I think a standard ball on a ballpoint pen is ~0.5 mm (.019") which means you might want to bump up to a 2048 (Standard Writing) or a 2968 (Broad Writing). I am afraid I do not either own so I have no direct experience.

Thanks for the suggestions. It gives me a good place to start.
