I want to add 5-10g without changing swing weight or balance point - where should I add lead? Throat? The racquet is good but feels like a toy. I could handle 10g more.

  • Profile (mm)22-26-23

  • Balance (mm)325
 
You can't add weight without a change in SW and keep the same balance. Anytime you add weight above the grip, you're adding something to the SW, If you add below the midpoint of the racket, you're changing balance.

Why are you trying to add mass?

You cannot add mass without affecting SW and balance. Since SW is expressed in Kg-cm², you could add the lead tape at or just below the balance point and have a low increase in SW. The formula for Delta SW is just m (in Kg)*cm*cm measured from the 10 cm mark. 5 grams is .005 Kg and 22.5 is the cm point or 2.5 Kg-cm².

Best non-obtrusive place to add weight is the top of the handle.

Best option is golf lead tape, which is 1 gram per inch, wrapped twice under the top of the grip.
