"well my biggest problem with my driver is I don't release on my follow through every time and so I end up slicing some of the time … what can I do to ensure that I release on my follow through?"
Releasing the hands is one of the biggest problems many golfers face today. To get a little more technical, the release is defined as the motion of the hands rotating through the impact zone. If the hands are late, i.e. don't release, the face will remain open at impact and the ever so common slice will manifest itself. The proper timing it takes to consistently keep the face square at impact is literally a never ending quest. So, rest assured the task is daunting, but, with good practice, it gets easier and easier. Mastery is never achieved but consistency is certainly obtainable.
A disclaimer should be mentioned before we talk about a solution. The brain often realizes the error and will try and fix the problem through its ignorant means of logic. The most common error in a self fix is to strengthen a grip. This is when you place your left hand in such a position that your left thumb is shifted well to the right side of the club. This also puts your right hand well underneath the grip. This erroneous placement gives the brain a false feeling of strength and a false notion of a postion that promotes rotating hands. What then occurs is 2 things: first, you position your hands stronger and you rotate you hands and you snap hook the drive and secondly, your brain tries to fix that problem and you actually inhibit your rotation to avoid the over rotation therefore resulting in a no release action through the impact zone. This common error reduces club head speed, therefore resulting in shorter distance and it increases inconsistency because of its lack of reliability. Your brain is your worst enemy here.
The best tip I have for getting your hands to rotate through impact is to practice full swings exaggerating the release. This practice is so exaggerated that your forearms will touch on the follow through. This exercise must be executed with a neutral grip, otherwise you will change your reputation from a slicer into a hooker, and we all know that nobody wants to be a hooker ;) you should not hit practice shots while trying to create muscle memory, this practice swing is simple to create a consistent feeling of the hands turning over at impact.
As you can see, in this picture below, my right hands has turned over completely, and I have the feeling that my right hand is now on top/above my left hand through the end of the swing. It is this feeling that you want to replicate as you practice my drill to get your hands to turn over.
