Verdict
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 softest serious 98 you can buy right now (61 RA plus ProKennex's moving-mass Kinetic chambers), with real spin and placement, but you supply the pace, so it's a demo for arm-sore control players, not a Clash substitute.
Yonex’s 1987 club classic—0.6 mm polyurethane that sits between Tourna’s chalky dry and Wilson Pro’s soft tack—$8 for a 3-pack, colors for days, the balanced overgrip Court List was missing.
