“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 Karbon Confort is Vairo's kind mid-tier: an 18K face over an EVA core in an even 375 g build, scoring a moderate 74/69 split with fair terms (comfort 69, tolerance 68) and honest handling (70). Value 82 is the headline again: an 18K face with Argentine heritage at arithmetic the establishment cannot match. The Confort tune takes enough edge off for regular club play without going fully soft. Between Vairos, the Speed hits a touch harder, the Confort forgives a touch more; both are pressure-priced. The thin European network remains the only real caveat.”
