How to do better "Graffiti stroke" text?

Trying to pull off a similar effect with some cursive type. Im running into a situation where the brush size needs to change as the stroke is being "painted" or else parts of the letter get drawn before they are supposed to due to the brush thickness, which is as small as I can make it and still fit the widest parts.

You can see in the "g" a part of the loop shows that should not have been drawn yet due to the brush thickness. It also causes an issue with the E.
