Lines appear pixel-y? ToonBoom 7

Hey folks! I was wondering if there was anyone here who may be able to suggest how to adjust my drawing tools (brush and pencil) to opporate more like a pen tool? Right now they’re giving me some harsh pixels around the edges as I try to traditionally animate something in ToonBoom 7 and 'smooth’ing the lines is only helping minimally. Any suggestions?

I have TBS v6 which allows me to adjust the Pen tips in the PEN menu.
Are you using a Cintiq, because that helps a bit.
