I notice that when I work with dowels a lot, I tend to shank when I go out on the course. I believe this is because I am aiming the shaft at the ball. When you trace with the shaft of the club, do you trace to a line inside the plane line (the shaft line)? In my desperation I have tried to visualize the shaft location at address or impact fix and aim to pass through that location - that seems to help me a bit. I have heard something about feeling the sweet spot but I can't seem to get that to work. Is it OK to try and aim the shaft rather than the sweet spot?
