I am planning to customize a racquet by putting lead tape at 3 and 9. The racquet is 9 points HL.
Adding the weight will affect balance and would like to know how.
Would the racquet become more head heavy? If so, the 9 points HL would become 7 points HL.
Is there a formula to determine this.
Lets say I would put 10 grams in total at 3 and 9.
In addition, how much would the swing weight increase.

Thanks

Spin Grim, the racquet will become less head light or head heavy, depending on how much weight you add. You need a balance board to determine this. It can't be calculated. You can calculate the increase in swingweight with the formula;

W=M*D^2/1000

Where W = increase in swingweight, M=the weight added in grams, D=distance from the butt end of the frame to the center point of the weight in CMs minus 10, squared.
