Joma Slam Anthracite/Green vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The Joma Slam Anthracite/Green is a basic entry-level diamond-shaped racket that leans toward power but delivers it inconsistently due to a relatively stiff, unrefined foam core and modest construction quality. The feel is somewhat harsh on off-centre hits, making it unforgiving for improper technique, and the sweet spot is noticeably limited compared to mid-range competitors. Beginner club players looking for an affordable first racket may find value here, but anyone progressing beyond the early stages will quickly outgrow its limitations.”

“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.”
