I am beginner to intermediate player, 67kgs/147lbs, 5' 8"/171cm tall. Medium swing speed but I am trying to build on it and make it fast, double backhand, gripsize 2 (4 1/4). I have been using the Ozone 7 (105 sq.in, 27.25 in. long, 1 pt. hl, 10.6oz strung, swingweight 325) since I started playing. I got a minor tendonitis on my right hand after 2 weeks. The Prince Ozone feels bigger than I like. I went to a more head-light and heavy racket the K Six-One 95 (18x20). Although a considerably smaller headsize and more difficult to play with when I was switching from the Prince to the Wilson I felt like my hand was massaged. So much better feel the K 6.1. 95. I played better with the K Six after some time and when I was switching back to the Prince it was even more difficult to play with... But the K Six-One 95 proves to be a bit heavier than I can handle while serving. My serves are totally mediocre with the Wilson while they are fine with the Prince for my level. MAybe it's more psychological because of the tendonitis but I want to dump the Prince. I feel it's big and not easy to manoeuvre. I am thinking of getting the Yonex RDS 003 and the Dunlop Aerogel 300... I was also considering the Wilson K Factor KPro Open and the Wilson K Factor KTour and the Yonex RDS 002 (not the Tour version)... I need your guidance because I can't demo any of the above... or any other racquet... Thanks a lot.
