Racket profile

Wilson Defyer 100 UL V1

The lightest Defyer at 265 g unstrung, with a 100 sq in head. This assessment uses published specifications, not a play-test.

Editorial verdict

Is it worth demoing?

Best for

Try it if easy preparation and low static weight matter more than the stability of the heavier Defyer models.

Think twice if

At 265 g, check stability and depth against faster incoming balls. A very light frame can be easy to swing without necessarily being the best match under pressure.

Alternatives worth demoing

Editorial shortlist based on published frame class and weight; compare on court.

Yonex

VCORE 100L 8th generation

A 280 g, 100 sq in option to compare spin and rally-ball shape. This assessment uses published specifications, not a play-test.

No recent UK quote recorded.

Trade-off: At 280 g, check stability against pace as well as quick preparation; a lower static weight does not prove a lower swingweight.

Dunlop

SX 300 Lite 2025

A 270 g, 100 sq in option to compare spin and rally-ball shape. This assessment uses published specifications, not a play-test.

No recent UK quote recorded.

Trade-off: At 270 g, check stability against pace as well as quick preparation; a lower static weight does not prove a lower swingweight.

Head

Extreme MP L 2026

280 g and 100 sq in: a current Extreme option to compare if you want a heavier, more dipping rally ball.

No recent UK quote recorded.

Trade-off: The lower static weight can make preparation easier, but test stability against pace and blocked returns before assuming lighter is better.

Strings and ownership

Use the manufacturer range above where it is published. Agree the material, thickness and starting tension with your stringer; there is no universal setup for this frame.

Buying used

Check bumper, hoop, throat, grommets and grip. Structural doubt overrides a cosmetic grade. Include replacement parts and a restring in the total.
