Re: Best score after playing for one yearjermzkill -- taking a lesson is a worthwhile investment because the grip will be a first order of business, but you will get several good ideas to work on. It is always easier to catch tendancies that are wrong earlier than later. Once you ingrain a habit like a bad grip, change is only harder -- but will still be worth it in the long run.
If you cannot afford a lesson, I would suggest giving up a round of golf and using that money for a lesson. At the least, go to the library and find Hogan's Five Fundamentals and study the grip, especially his left hand.
Good luck and good golf,
