the grip is very important,i think that many of the top golfers who have a good grip can say that wrist exercise plays a big part in the actual grip lock,i have heard that rotating the wrist clockwise for 10 seconds then counter clockwise for the same period of time can help with the development of strong wrists which they say may lead to a better grip,strong grip is very useful when it comes to making a putt whether long or short when in the wind,the grip will help the golfer make up the resistance that the wind causes enabling the golfer with a good grip to make the putt like it is being made under normal conditions
