Proton Series One Project Black verdict
A thermoformed unibody built around stability. The foam walls push twist weight to the top of our measured range, which is why off-center drives still land deep.
Six Zero Ruby verdict
Six Zero's answer to the hybrid trend, and the most balanced paddle in our 2026 test group. Very few weaknesses at this price.
The verdict

- Which is better, the Proton Series One Project Black or the Six Zero Ruby?
- Proton Series One Project Black carries the higher overall Paddle IQ score (83.8 vs 83.5), but IQ is a weighted average. On the trait that separates them most — swing weight — Proton Series One Project Black leads by 6 points.
- Which one is faster at the kitchen line?
- Six Zero Ruby, at 114 kg·cm² swing weight against 117 for Proton Series One Project Black. Lower swing weight is the single best predictor of hand speed in fast exchanges.
- Which paddle has more power, the Proton Series One Project Black or the Six Zero Ruby?
- Proton Series One Project Black measures 86 on power against 85 for Six Zero Ruby. That comes from a 16 mm Thermoformed unibody with foam walls core swinging at 117 kg·cm² — mass behind the ball, not face material.
- Which one gives more control and touch?
- Proton Series One Project Black at 86 versus 86. Its 16 mm core holds the ball on the face slightly longer, which is what makes resets and dinks land shorter.
- Which paddle spins the ball more?
- Proton Series One Project Black scores 90 for spin off its Raw carbon fiber face, against 88 for the Raw T700 carbon face on Six Zero Ruby. In practice a 2-point gap is small enough that technique matters more.
- Which is more forgiving on off-center hits?
- Proton Series One Project Black, with 7 twist weight against 6.6. Higher twist weight means the face rotates less when you miss the middle, and Six Zero Ruby carries the higher forgiveness score (81) as a result.
- Is the price difference worth it?
- Six Zero Ruby costs $160, $40 less. Whether that gap is worth closing depends on whether you actually use the traits it trades away — check the head-to-head DNA bars above before paying up.
- Do they use the same core and face?
- Proton Series One Project Black: 16 mm Thermoformed unibody with foam walls core with a Raw carbon fiber face. Six Zero Ruby: 16 mm Thermoformed polymer core with a Raw T700 carbon face.
- Which is better for a two-handed backhand?
- Proton Series One Project Black, at 5.5 in of handle against 5.4 in. Anything under 5.25 in forces you to choke the bottom hand onto the face bevel, which Proton Series One Project Black avoids.
- Which one is better for beginners?
- Six Zero Ruby is the safer first paddle here: forgiveness 81 and sweet spot 82 mean fewer mishits while your contact point is still inconsistent. Proton Series One Project Black rewards a repeatable swing and can feel unstable before that.
- Which is lighter in the hand?
- Six Zero Ruby at 8.2 oz against 8.3 oz. Static weight matters for arm fatigue and elbow comfort; swing weight (114 vs 117) is what you feel mid-rally.
- Is it worth upgrading from the Six Zero Ruby to the Proton Series One Project Black?
- Only if you need what it actually adds. Proton Series One Project Black leads on swing weight by 6 points; everything else is within 6 points. At $200 vs $160, the money is better spent elsewhere unless that one trait is your weak spot.
