My Swing (Casey)

I am not an expert by any stretch but from the lessons I am taking I might suggest that you try shortening your backswing and staying more in control on your follow through. For the follow through my teacher suggests I envision that I am trying to throw the club head to the target, keeping it low. This has helped me release my hand at impact and it ends up shortening my follow through. The end result is that my entire swing is more in control, leaving less to chance. I think you have a good swing, you're turning your body, driving your hips through, etc. It just appears to me that you are a little loose at the top of your back swing and during your follow through. Please take what I say with a grain of salt because I'm working on my swing as well, and I am not a teacher. There are more qualified persons on the TST.

Same as Cooke I am not a teaching professional but there are a few things I noticed mostly with the set up, the swing is kind of choppy so its hard to say. First it looks like you are leaning back on your heels in your set up. You want a more athletic stance, knees flexed and very stable. Now my next tip take with a grain of salt it works very well for me but a lot of people will say otherwise. Try keeping you back knee (right) flexed all the way through the swing. It helps keep you from over rotating back to far and it gives you a good base to push off on with that back leg. The swing is hard to tell I only watched the driver since that is what you want to fix. I find it hard to believe you skying balls with a swing that is so flat, most of your swing balls with a driver is because you get to steep. You may want try teeing it a bit lower if its a big problem, that might be a simple solution. You are a bit over the top with the swing but nothing that looked horrible from that video. I did watch that 8i video and it seems like you are laying back through the shot and not getting your weight back to your front foot which could be why that ball shot right off the club face.

Just a few things I noticed.

Back swing is too long. Keep left arm straight at the top of swing

Left knee bends too much- keep straighter.

Don't sway as much.

Definitely get a haircut, and then shorten your back swing. 

To me, the reason you are occasionally skying your driver and hitting the occasional slice with it is because of your angle of attack into the ball.  It is very steep for your driver.  How is your ball flight with your long irons also?  Ball flight laws would suggest that you have a square club face so I would not think it has anything to do with the clubhead.  When you get steep on a driver the things you describe can occur.  A drill that I have found to be very useful for this is attached in the link below.  Let me know how you get on.

Nice natural swing. Right heel a little noisey as well as left knee. Quieting down that action will help keep your head still. Your setup will also affect launch. But I couldn't tell. Nose, shirt button over left toe..
