Let your legs do the work. If your lower body is moving and turning, your upper body has to as well. Let it happen with as little conscious input from you as possible.
I have only ever had two putters in the past 15 years and the first being a Ping copy which I thoroughly enjoyed for about eight years however when the Odyssey long putter emerged I just fell in love with it and I even have a spare just in case it gets broke or stolen as this is one of the most important pieces of golf equipment in my bag and something that I would not want to be without.
You have not control, not to mention your confidence completely leaves you at the time you need it the most. And we all know how important confidence is when standing on the tee, about to smash it down the fairway.
Once you get used to moving through impact in this way, you will find the rest of your swing setting up to make this movement with no explicit effort on your part. The result will be a long, straight shot.
Imaging for one minute that your body is a door with spring loaded hinges. If your are a right handed golfer, then your right foot and right side would be the hing part of the door. When you begin your back swing, you will be shifting most of... say about 80% of your weight around the hinges.
There are days when the putter's hot and the chipping cold. The driving is good and the irons shots bad. The short game, the long game or any combination within the game all seem to be fighting for domination.
A golfer can use a towel to dry their hands before making a shot in order to keep their club from slipping in their hand. Towels are also great for cleaning grime off of the club heads before it becomes dried on. A golf glove is also a necessity for many golfers. A golf glove will give your hands a non-slip grip on the club. Finally, golf shoes are quite useful as beginners golf. Most courses don't require them as a part of the dress code, but they will help the golfer with their swing by eliminating the slipping that sometimes occurs.
