This is something that is very annoying in the Golf Industry. Golf technology is very comparable to cell phone technology. Although, they are ever changing and coming out with new technology every six months. In the end, the cell phone still makes calls and the golf club still wacks balls. If you choose to get caught up in which club is smoother, hits it further, etc. then you will drive yourself nuts. I would say to find a club you like and stick with it for 2-3 years. That is a good enough amount of time to let golf equipment really get better.
