Hosel Design mainly affects the directional ball flight patterns. Directional ball flight patterns are mainly a function of how much or how little "offset" is designed into a club. Hosel offset is defined as the distance from the farthest front portion of the hosel to the farthest front portion of the face on its centerline.

When a club has too much offset a player might:

             1.  Aim to the right of the target
             2.  Have weak grip positions
             3.  Have a tendency to open the clubface
             4.  Have no release through the ball
             5.  Have shallow flat backswings

 The player is primarily trying to keep the ball from going left.

When a club doesn’t have enough offset a player might:

             1.  Aim the left of the target
             2.  Have strong grip positions
             3.  Have a tendency to close the clubface
             4.  Overwork the hands through the swing
             5.  Have steep upright swings
