A lot of people agree with me but a lot of people prefer one version over another. I know people who prefer the Chinese versions. I know people who prefer the Austrian versions. I know people, like me, who think they play very similarly. To each his own.
All Pro Tour 280/630's (and Radicals and Prestiges) are great rackets IMHO.
