Generally the plane you will swing on is dictated by the clubs lie angle, set the club flatly soled on the ground, your startup and backstroke will go backwards upwards and inwards simultaneously, the hands and clubhead should travel up the same line as the clubs intended lie angle to about the halfway point in the swing then it will likely shift up to a slightly steeper plane, I realize a good video is necessary to really demonstrate this I will try to put one up ASAP.
