A couple of months ago I purchased a Zepp sensor which alongside lessons I have used to work on my slice. after hitting 1000's of balls I have got my swing on a neutral plane either + 1 or 2 degrees or - 1 or 2 degrees. Providing my swing path is good which my Zepp is telling me it is the reason for my misses must be the angle of the clubface? My misses are either a straight pull left (I am right handed) or a shot that starts straight and fades away right. Look forward to peoples ideas on this one.
