285 g and 99 sq in: a current Shift option to compare if you want a heavier, more dipping rally ball.
The Tennis Shop editorial · Manufacturer specification source checked 7 October 2026
Who should demo it?
Demo the Shift 99L if you want a heavier, more dipping rally ball. Keep the strings and grip setup close to your current racket so you are comparing the frame, not a completely different setup.
What to watch for
The lower static weight can make preparation easier, but test stability against pace and blocked returns before assuming lighter is better.
A useful on-court test
Use comparable strings, tension and grip size. Test rally depth, firm returns, second serves and quick exchanges, then finish with points after at least 30 minutes. Take your current racket as the baseline.
Match the exact generation, grip size and stringing status. For an unstrung frame, add the string set, labour and delivery before comparing the ready-to-play cost.
