Nothing beats the classic look of blade irons, except the forgiveness of cavity backs. While it is tempting to buy a new set of clubs based on looks it can seriously hurt your scores. Golf club manufacturers spend millions of dollars on research and development to build a club that is more forgiving and well suited to 99% of the golfing public. The fact is that people usually buy what they see professionals playing with and it can be a big mistake.
The biggest part of the problem is that the clubs professionals and top amateurs play with are built specifically for them, and not just shaft flex and length. Professionals spend countless hours with fitters to determine the best sole grind, shaft weight, kick point, grip size, swing weight, lie, head shape and material before deciding on a new set of irons, woods, or putter. While this kind of service is available to the public you can expect to spend $5,000-$10,000 on a set of clubs depending on the shaft options and fitting charges. This is something that is just not realistic to the average person.
The absolute best thing any amateur golfer can do is find a demo day and hit as many different clubs as possible. Your local course will often host demo days. If they do not have any scheduled feel free to ask them to look into it. It offers the average golfer to get a glimpse of what a tour player experiences. While the average demo day is not as intense or scientific they should offer plenty of options for the average golfer. Every major golf club manufacturer has upcoming demo days listed on their websites as well. If you cannot find a demo day ask your local professional for a fitting. They will be able to explain the benefits of different club designs and make sure you order what works best with your swing.
Going to the demo day or fitting with an open mind is perhaps the most important factor. It is easy to see someone win a PGA Tour event with a new driver and want to run out and get it. The fact is that it may not help your game at all. I know several fantastic golfers that are playing with Ping irons from the 1980′s and can still compete with anyone around. Just be sure to go into the process willing to try anything if it will help your game. By looking in a different direction you may find something that fits just right.
