There's an old guy on one of the municipal courses i play, that walks the course with a bag and 4 clubs. A 3 wood, 4 iron, 8 iron and putter.
i swear to you the guy goes round in a lower score than most of the people i know. To steal a phrase from Tiger Woods golf, he doesnt 'rip it', but lets the club do the work. everytime its straight, gets good distance (although not as far as when you try to mash the ball into december) and knows exactly where its going.
Over hitting is the biggest problem for a lot of people.
