Such considerations cut both ways. Suppose you wanted to copy some
selection set containing one of these into another drawing at a different
scale. Different arrowhead sizes would be appropriate. With leaders using
a dimension Style, presumably Dimscale would be appropriately different in
the new drawing, and simply "updating" the leaders would correct the
arrowhead size of both (all) arrows at once. Imagine what it would take to
do the same with a variable-width polyline, requiring adjusting the length
of the tapering arrowhead portions as well as their width at the wider ends,
and doing both of those things for both arrowheads. (It would probably be
easier to draw it again.) And if the angle of the thing is oddball.... And
if the copied stuff contains a whole bunch of them....
Another potential problem with stretching the polyline variety is that, even
if you're stretching in the end-to-end direction so the arrowheads remain
pointing in the same direction as the line between them, if you don't happen
to include BOTH ENDS of the arrowhead in the selection crossing window, the
line part stays where it is and you get a whacked-out arrowhead. With the
leader variety, all you need to catch is the tip of the arrow (or a lot more
than that -- it doesn't make any difference). The arrowhead always remains
the same size, and is always oriented right in relation to the line.
