- Ronbus R4 Pulsar, at 113 kg·cm² swing weight against 114 for Six Zero Ruby. Lower swing weight is the single best predictor of hand speed in fast exchanges.
- Which paddle has more power, the Ronbus R4 Pulsar or the Six Zero Ruby?
- Ronbus R4 Pulsar scores 88 for power against 85 for Six Zero Ruby. That comes from a 14 mm Thermoformed polypropylene with foam walls core swinging at 113 kg·cm² — mass behind the ball, not face material.
- Which one gives more control and touch?
- Six Zero Ruby at 86 versus 82. 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?
- Too close to call — neither has an advantage here. Both score 88 for spin off the same Raw T700 carbon face.
- Which is more forgiving on off-center hits?
- Ronbus R4 Pulsar, with the higher forgiveness score (82 vs 81). Six Zero Ruby actually carries the higher twist weight (6.6 vs 6.5), but Ronbus R4 Pulsar makes it back on sweet spot (84) and overall face stability.
- Is the price difference worth it?

- Which is better for a two-handed backhand?

- Which one is better for beginners?

- Which is lighter in the hand?
- Ronbus R4 Pulsar at 8.1 oz against 8.2 oz. Static weight matters for arm fatigue and elbow comfort; swing weight (113 vs 114) is what you feel mid-rally.

- Only if you need what it actually adds. Ronbus R4 Pulsar leads on swing weight by 6 points; everything else is within 6 points. At $160 vs $160, the money is better spent elsewhere unless that one trait is your weak spot.
