Dunlop SX 300 (2025) vs Penn Championship Extra Duty vs Yonex VCORE 100 8th Gen (2026)

Dunlop’s teal/yellow spin 100—TW topspin 9.1, $250 street, the empty-brand Aero/VCORE alt Court List was missing—not the first spin demo for most, but a real primary if you want shape cheaper and a touch more directed than yellow Aero.

America's default can, the official ball of USTA Leagues for about $3.50 a can by the case, but it's priced for volume and plays like it, with reviewers saying it fluffs and goes flat in a set or two.

Yonex’s club spin flagship opposite Pure Aero—Ruby Red 100 that loads the ball with snapback, pockets more than it punishes, and belongs on the short demo list if Aero feels too boardy.
