Being a better coach than a player as I am. I suggest staying with 10.5 degree driver. At this point all. A new club will do is inspire confidence. Which is a good thing. Now to keep that confidence try to envision the back of your left hand in line with the club face. In essence the feel will be to smack the ball with a back hand slap. If the ball is still moving right with no hight. Then move the ball up in your stance. As a last resort to conquer the slice, try and hit the ball with the toe of the club on your downswing. You can’t do it perse, but the ball will have a hard time going right anymore.
