For anyone who has ever played the game, the problem of hitting the ball too long or short is a tough one. Almost all amateur golfers overestimate their distances with all clubs. Most amateur golfers look to their "career long" distance with a club (i.e. because three years ago they jacked a 7 iron 170). The best and cheapest way to find correct distances is probably going to a flat range and hitting a series of shots to find your average. The problem of hitting the ball too short is usually incorrectly credited to hitting a weak shot.
