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.
The lighter version of the Ultra 100, at 280 g unstrung and swingweight 310, with easy power and spin for improving players, but it runs out of stability against heavy balls and costs full flagship money.
