Another option that you could think about is flattening out your clubs to help with your misses that you said went left. I agree that if you are flipping at the ball at impact will cause you to hit the ball higher and miss it to the left. The other option is getting dgs400 and soft stepping those to play like a s300, because s4 is a little heavier than s3. That will help with getting the ball flight down and will go a little less left.
