I'm interested in people's experiences with 18x20 string-pattern racquets (e.g., Wilson N6.1 95, Prestige, Volkl, Technifiber, Yonex RDX HD etc.), as well as their experiences with different types of string for those racquets. Background: I decided the ProKennex Ki-5 PSE (BDE 16 gut) I've been using is too heavy (13 oz.) for me. I demoed the Wilson N6.1 95 16x18 and 18x20 and was surprised to find I preferred the 18x20 from the start. I briefly demoed the Head Flex Pt Prestige and Volkl DNX-10, & thought the Prestige was a bit stiff, & DNX too low powered. However, I used the DNX a couple days later for drills, and started to REALLY like the racquet. Would I also like the Prestige with softer string? I'm 45, 4.0, had some tennis elbow problems (1 H BH) & tend to be a consistent, not power player (some might say counter-puncher). My strokes became longer after switching from a Wilson 5.3 Hammer to the Ki-5 PSE a couple years ago.
