Hi Everyone,

Firstly I would like to thank Travlerajm and every other member who has contributed to that immense amount of information on racquet customization.

Secondly Travlerajm I was wondering if you have even managed to created a step by step procedure for creating a polarized racquet? I have created myself a worksheet for a depolarized a racquet based on your previous posts that includes calculating addition weight needed and weight placement, it also calculates the MgR/I and MR^2 values as well as swingweight prediction (from your posts on your racquet setup).

However after customizing my racquet to a depolarized setup I found that it just was not as maneuverable (too heavy) as I would have liked, especially for serves. I like to played with spin and found this racquet not able to generate enough as I would have liked. I understand that depolarized racquets are not great spin producers.

My current customized racquet specs are as follows:
Static weight: 352g (12.42 oz)
Balance: 32.0cm (12.61 inch)
SW (10cm): 340 kg-cm^2
Effective SW (4cm): ~448 kg-cm^2
MgR/I: 20.88
MR^2: 360.90

I have another stock racquet that has the following specs (to modify into a polarized setup).
Static weight: 336g (11.85 oz)
Balance: 32.7cm (12.87 inch)
SW (10cm): 336 kg-cm^2
Effective SW (4cm): ~440 kg-cm^2
MgR/I: 20.53
MR^2: 352.97

I feel a racquet setup around 12-12.2 oz would be best.

If anyone would be willing to help that would be much appreciated. If you require and more information please do not hesitate to ask.

Kind Regards,
FALC

As I understand, Travlerajm's method aims to get an ideal combination of specs to optimize swingmechanics.
The ideal sw (SW2) is around 365, with an MgR/I of around 21 and MR^2 of around 385.

With your radical, it's impossible to get at 365 SW and 21 MgR/I without making it heavier than 12.2 oz. I think you'd need to go up to at least 360 or 370 grams to get a reasonable balance point.

And then it's still difficult. I don't remember seeing a specific method to get there since it greatly depends on starting specs. Your best bet, would be to try stuff using http://twu.tennis-warehouse.com/learning_center/customizationReverse.php and an excelsheet. Or hope corners or travler have a good method for getting there.

Help!

Hi Corners or Travler,

It would be much appreciated if you could provide some feedback on my current racquet setup, I have been fiddling with it for hours and some guidance would be fantastic, I feel lost.

Thank you cellofaan for responding .

Regards,
FALC

oh man.. i also am curious about these stuff about optimizing racquets..

ive been swinging pc600 for most of my life man.. it did weigh in at about 404 grams, 31.0cm headlight, what's funny is that in both the mgr/i and mr^2 equation and sw i got them in the range of optimum..

i dont know whether its just a coincidence or the equation actually really works? :S
