re: sky ball
A couple of thoughts that may help you.
1) ball should be set up off your left foot
2) a horizontal spine tilt to the right. This does two things. It promotes a inside takeaway, which will give you a go inside to outside swing. It also keeps 60 percent of your weight on your right side, whiich gives you a upper driving swing.
3) keep your head behind the ball through out the swing. This help provides contact with the ball on the upswing. Jack Nicklaus preached this method.
4) make sure when you tee up the ball, half of the ball is tee'd above the driver head. This is especially important with bigger head drivers.
5) swing through the ball. A trick I like to do is make sure my right shoulder is pointing at the target line during my follow through.
Good Luck.
