Verdict
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-player control stick—surgical 97 aim, buttery FlexCon pocketing, and enough spin to keep full cuts honest.
