Hi,
I think there is a misunderstanding:
As far as I understood the suggestion is not to use an other icon, but to place the icon (an arrow) in an other way:
Not the center of tbe arrow marks the current position, but the tip of the arrow.
Disadvantage of placing the center of the arrow on current position: The tip of the arrow covers (hides) the part of the map you will enter soon.
This can be solved by placing the tip of the arrow on current position.
