The cooler weather and nursing a back sprain has left me watching lots of video on golf. One noted instructor says that there is at least 4 more yards in every golfer. You need to swing faster. Another PGA player says he only swings about 80%. For me if I try to swing 100% the chances of keeping a ball in the fairway or hit a green is slim to none vs. a 80% swing. We all want to hit the ball further but where do you give up control over distance ?
