Bear in mind that polylines are defined with geographic coordinates. It will not be easy to make arrowheads which do not vary in size with zoom level. Encoded polylines may make that possible because you can specify points to plot at each zoom level, but I've not seen encoding used that way before. To answer the original question, since you seem ill-disposed to try it: I don't think there will be an enormous difference between 100 polylines with icons and 100 polylines with VML/SVG arrows. If there *is* a difference, the VML/SVG should be slightly better because the arrows are not carrying all the GIcon() baggage which you don't really need. BUT the principal difficulty will be that many polylines in the first place; the way arrows are plotted is moot.
