Pros

  • 15K carbon faces deliver 9/10 power — a weave density that sits between Siux's 12K and higher-tier 21K or 24K options — providing the ideal stiffness balance for Stupa's hard-hitting game where face rigidity amplifies swing force without reaching the extreme technical demands of the highest weave densities
  • Hard EVA core provides a fast, firm ball response on drives and overheads, preventing energy loss through core compression that softer foam grades introduce, supporting the 9/10 power ceiling consistently across long matches
  • Sandy rough surface finish creates pronounced ball friction across the teardrop face, enabling Stupa's signature heavy topspin and slice effects — the sandy texture generates more friction than standard rough patterns, amplifying effect generation
  • Dual Pro Grip Dampeners — two anti-vibration dampeners integrated into the frame — specifically target the vibration that Hard EVA and 15K carbon generate on off-center hits, protecting Stupa's arm during the high-volume professional training loads his schedule demands
  • Even teardrop balance achieves 8/10 on both control and maneuverability simultaneously, confirming the frame handles Stupa's all-court transitions between net play and baseline defense without a pronounced directional bias

Cons

  • Ball exit sits at 7/10 — the lowest figure in the spec sheet — because the Hard EVA core and 15K carbon stiffness prioritize energy transfer over elastic springback, meaning pace comes from swing force not frame rebound
  • Medium-hard touch on a Hard EVA frame still transmits significant vibration on off-center contacts — players below advanced technical level will find the construction punishing on mis-hits
  • Even balance at 355–375 g offers no head-heavy advantage for maximum overhead smash momentum — players targeting the absolute highest aerial pace would benefit from a head-heavy diamond alternative
