My home course is hilly and I rarely get a level lie. 7 times out of 10 I'm dealing with downhill, uphill, sidehill, and combinations of the three.
There is no practice station on the range for dealing with the above, you have to adjust your machine to the situation at hand.
I'd like to start with how to play a downhill or uphill shot. Is the adjustment simply ball more forward or backward in the stance, respectively? Or do we attempt to get the shoulders more parallel to the ground in setup and leave ball position as though it's a level lie?
