I have trouble hitting the ding most times. The R11 irons have fast meters, the long irons are super quick. So I don't try to hit the ding anymore.
I'm usually slightly either side of it depending on wind and with a bit of adjusting with the aim, I find it easier.
Also if your using Chrome... Flash Version ending with .268 and .271 are the one to have and disable the pepperflash file.
