Trouble is mate we all have not got your natural talent
Unless there's a bunker in the way and the pin is cut on the short side.
I agree, that's pretty simple, and I know someone who virtually always uses a 9-iron to chip.
But there are many situations where even a successful one of those will leave you a long way from the pin! That's where chipping with higher loft wedges comes into its own!
I only use higher loft if I have to clear something like a bunker. Otherwise keep it low.
