In small sizes, some manufacturers don't label small cord in fractional sizes, like 2.5mm. So, a 2mm line may be small and a 4mm line large, as though so a nominal 3mm line can fit in to the product list.
That is not to minimize differences in coatings mfgs use to protect the cord and alter feel. But, coatings seem to have small effect on diameters and weights. If Dynaglide seems stiff, that would be what arborists would want for throwing or shooting a bag through leaves and branches with minimized tangling.
