where do you add weight to reduce frame shock/vibration

[ricardo]

According to this site (http://twu.tennis-warehouse.com/learning_center/vibration_explanation.php), adding weight near the tip or the middle of the racket (13.5""), will reduce frame shock/vibration more than adding weight in any other part of the racket including at 3/9 points.

any comments based on your own experience???

3 and 9 will help with twisting from off center hits which was where most of my vibration was coming from.
