Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk scores 91/100 against 79/100 for the Varlion Bourne Summum Prisma Radio. Its biggest edge is power (+10). The Varlion Bourne Summum Prisma Radio answers back on comfort (+9). On price, the Varlion Bourne Summum Prisma Radio is currently €34 cheaper.
“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 Bourne Summum Prisma Radio W carries Varlion's serious Bourne Summum identity into a women's-specific build, pairing a supersoft EVA core with a 12K carbon face for genuine attacking output that stays comfortable to generate. Varlion's AirFlow venting adds real handling speed.”
