“The Vertex Junior 2026 is the diamond-profile member of Bullpadel's junior line, offered in a 335 to 345 g spread: power 70 with balanced terms (comfort 71, tolerance 72) and quick handling (73). Face documentation is incomplete. Value 80 continues the family's correct economics. The weight options are the practical differentiator at this age group, where six months changes everything. Between the Vertex juniors, this edition's spread and diamond geometry suit growing attackers best; the fixed-weight editions suit kids whose size has settled. All of them teach properly.”
“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.”
