All cybers have the same shape ears and are mapped that way - so putting in different ears every time didn't make a lot of sense to me. It is the perfect shot - face on with the ear.. using profile player pics - you see a different angle of the ear, and to fit that in properly every time, getting the right angle and shape, etc.. is a waste of time and a waste of effort.
As well, the ears are also placed almost exactly the identical spot in every cyber, so I have made myself an ear-template, if you will - that I put in the very last thing when I make my cybers.

In any regard, I don't think an authentic ear is necessary in cybers, unless it's
really a unique-shaped ear on a particular player, etc.
