If you slices, likely because you allow the clubhead to move ahead of the path of your hand on the way to the ball overhead. The club should stay behind your hand path until you start to swing at impact.
Next time you train, put the ball off your back foot like you see I’ve done here. Set as normal and rock.
Using your peripheral vision as you start down, use the second ball as a guide for your clubhead, making sure it stays behind the ball instead of moving in front of it (as in away from you).
The trick is to allow your trail arm to extend while keeping the twist on the trail wrist (ie how it’s placed at the top) as long as possible.
Club head behind the hand path: no parts and lots of power.
Try it.
