The Wilson Blade 98 (18x20) v9 is a advanced-level racquet with a stiffness rating of 64 RA. Its 18x20 dense pattern prioritises control and consistency, but limits spin generation — making string selection particularly important. Our picks lean toward feel, control, and feedback for advanced technique.

General guidance only — not professional advice. Tension preference is personal and varies by playing style. Always stay within the manufacturer's recommended range. The dense 18x20 pattern plays stiffer, so many players prefer the lower end of the range.
