“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.”
“The Black Mamba Radical 12K 3.0 continues Vibor-A's most famous line with a 12K carbon layup over an EVA core, and the strike has that dense, immediate character the Mamba name trades on. Power 85 finishes points; the even-balanced hybrid head keeps things orderly enough for control 70 to remain usable. Comfort 65 and tolerance 64 hold the familiar strict terms, and weight documentation is incomplete for this build, so check the specimen. Value 66 reflects premium pricing on a mid-table card. For players drawn to the Mamba mythology, the racket delivers the promised bite; comparison shoppers will find friendlier numbers elsewhere.”
