Dear Mr. Shin Thanks for your question, I assuming that long distance mean’s you may questioning a driver shot. The longer shot needs to power to increase club head speed and square impact. In order to do that your stance little bit wider than normal and weighted sixty percent your right foot and forty to left for your stability.(in case you are right handy) The most important thing is to match your club-head speed to your body speed synchronized. If you throw the club-head with the wrists, you're stuck with a club-length lever. Let the hands lead the club-head and you extend your lever exponentially. At impact far ahead of the ball your hands than club-head. I have several swing images for you to look at it. Please, check BBS contents. Thanks for your patient. Warmest regards. Lucas Yun
