Ryan, one of the gentlemen I work with at the course shared a few tips with me today regarding the golf ball's lie above or below your feet since I was having trouble with the ball's straight flight. I was always told to choke up on the club when the ball's lie was above my feet, he added that moving the ball back in the stance beyond center (in some cases closer to the back foot's heel) would help with it going straight. He also shared that when the ball's lie was below the feet to open the width of the stance. Thanks Ryan I'll try it and get back to you. Following are two videos that also shed some light with this ball lie situation.
I found on youtube a video by jcmsolo that had a very clear explanation on how various club's loft creates different scenarios for the uphill lie.
Here is the other direction wth the ball below your feet.
