I prefer to use full backspin and usually use 1 club more to make sure I get up the ridge on the green.The BS enables the ball to check quickly on the green.
It doesn't usually roll back because you are usually hitting a med to long iron into the green.
I always approach from the left side as the ball runs nicely up to the hole coming in from this angle.
If there is a strong cross wind from the right say 20MPH then I would play the wind as if it was 15 MPH and this will take me slightly left of pin which I believe is the way to approach this green.Again coming in from my favourite angle.
Hope this helps a little.
