Who should pick which
- Head size: Yonex Ezone 105 (2025) is 38.7 cm² higher. That means a bigger head, so a larger sweet zone and more forgiveness on mishits — the other gives you a smaller head, so tighter dispersion and more predictable control.
- Weight, unstrung: Wilson Shift 99 v1 (2024) is 25 g higher. That means more mass, so more plough-through and more to swing late in a match — the other gives you less weight, so easier to accelerate and easier to get round on fast returns.
Differences are computed from published specs only. Where a value is missing for either racket the row is marked incomplete and excluded from this list — an inference across a missing number is a guess, not a comparison.
