A smaller ball interpolated exposes more of the surface to a faster moving cutter, leading to a better finish. but, the smaller cutter can flex more. hence the need to balance these two factors. if you have a 4th axis or 5-axis mill, you can try “sturz” milling to combat the slow moving tip. see below for.
