I tried a proportional stringing pattern (Sergetti @ sergetti .com) and I liked it a lot. But using that process can be quite expensive with multiple rackets, tensions, and strings so I thought I test out some other alternatives. I'm going to use the spreadsheet diredesire has on his site (http://diredesire.com/tennis/TW/ProportionalStringing.xls) and the USRSA has a calculator on their site. I've contacted diredesire and he does not have any other instructions other than what is in his spreadsheet. Does anyone else have any more information on the process? Just out of curiosity has anyone ever tried the USRSA proportional stringing system or any other proportional stringing methods? I sure would like to hear from you if you have. EDIT: It's best to open diredesire's spreadsheet on a PC with MS Excel. Once you input the link it auto downloads the file and you can go to your download folder and open the file.
