“The Equation Advanced Series shares its women's sibling's HR3 Hard EVA core and round, fibreglass-faced build, aimed at an improving player who wants genuine performance material without flagship pricing. The carbon frame and anti-vibration system add real durability and comfort on top of the core's added pop.”
“Franco Stupaczuk's Shadow Red ST5 is built to attack: power 90 with control 78 is a proper first-strike profile, and the confirmed even balance at 365 g explains why it feels quicker between shots than its hitting power implies. Blocks and counters stay manageable, then the same frame turns a short lob into a finished point. The firm side is unavoidable: comfort 67 and tolerance 66 mean mishits are felt and punished. Beyond balance and weight, full spec for this colourway is unconfirmed, so try before you buy. For aggressive all-court players it is a convincing signature frame.”
