enter This racquet was used by so many Wilson Pro Players it is impossible to find a player image that will do it justice! It looks like the very racquet that Stephan Edberg used for most of his career.
https://marcosgerente.com.br/d1zpm5bmtf This is not a West Indies version but appears to be one of the first models manufactured in Taiwan. This racquet proudly presents the composition on the shaft as 80% Graphite + 20% Kevlar™
here This racquet is unique in that it does not have a “stiffness index” on it anywhere. The SI is normally something like 6.0, 6.1, etc. As you will see in the data below this racquet is not ultra stiff.
follow link As with many of the “ProStaff” racquets this one is fitted with the famous Fairway grip. This is truly the “Classic” ProStaff.

https://traffordhistory.org/lookingback/dhqvx5nttg Hello, could you tell me how you calculate the average cross string and main string spacing? I play with a Wilson FST 99 18 x 19 and I’m trying to figure out why I get ample spin on groundstokes but a little less than I need on serve. Thank You!
https://luisfernandocastro.com/sq4t62574 Hi, Nolan, and thanks for the message.
Buy Diazepam 30 Mg Do you know what your string bed stiffness is when it is fresh? What string do you normally use?
https://semnul.com/creative-mathematics/?p=ghqdig3sm2c Actually the calculation is only valid for a racquet that does not distort during the stringing process so the natural ratio of your racquet will be the ratio of main string tension to cross string tension.
https://trevabrandonscharf.com/rbgq4oqzw That is, if you put the main strings in at 60 pounds for example the cross strings will be about 37-40 pounds. This can be measured using a StringMeter or similar device.
Buy Valium England There is not much you can do about this on most stringing machines but in your case I would consider using a lower tension on both the main and cross string.
