Hi, looking to do some modifications on my 18x20 93p. What are some modifications you have done for the 93p that you recommend trying out? Thanks in advance
What works best for others may no necessarily be best for you. You should Have an idea of what you’re trying to to with your modification on the racket. I would prefer add mass in the head somewhere under the bumper guard and in the handle under the grip or over wrap. Once I find what I like best I can place the mass under the bumper and grip. I would advise raising the SW or Inertia in small increments to begin with. If you place weight in the head place the same amount of weight in the handle so the the weight and distance above and below the balance point is the same. This way the balance remains the same. Assuming you racket has a balance of 31.5 cm (strung) you could easily place your weight 30 cm above and below the balance (1.5 cm and 61.5 cm.) Now all you need to do is to calculate how much lead you need. Assuming you want to add 3 SW point you could use the I = mr^2 formula to get the weight needed. 3 = m*30*30 = 3.33 g or .00333 kg. If your using 1/4” lead tape I’ve found 1 g is 11 cm long. So 3.33*11 = 36.63 cm.I tossed some lead around 10 & 2 and immediately took it off after one session. Balance felt off without also adding subsequent weight in the handle. I think tinkering with strings is more the way to go with this frame.
This is the modification I would make if I owned one, minus the lead. If I had one close to spec I would remove the leather grip, reducing the weight by 10g and moving balance more head heavy. Then it would come in at same weight and balance as my PS90 Asian version, but with higher twist weight.I felt stock specs were too headlight and not enough twistweight. Made the following mods:
- Switched the leather grip with synthetic (Prince ResiThin).
- Added 4g of lead at 3/9 o'clock.
Really didn't like the racquet before, like it with the mods.
