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.
Ronbus R4 Pulsar verdict
Ronbus swings for pace with a 14 mm foam-walled build. Power 88 and pop 86 at $160 is the best price-to-punch ratio we have measured this year.
The verdict
Measured on the same 15-trait test, the clearest separation is maneuverability: Ronbus R4 Pulsar scores 78 against 72 for Proton Series One Project Black — a 6-point gap. They are effectively level on power, spin, forgiveness, so those traits should not decide the purchase. Ronbus R4 Pulsar is $40 cheaper at $160.

- Which is better, the Proton Series One Project Black or the Ronbus R4 Pulsar?
- 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 — maneuverability — Ronbus R4 Pulsar leads by 6 points.
- Which one is faster at the kitchen line?
- Ronbus R4 Pulsar, at 113 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 Ronbus R4 Pulsar?
- Ronbus R4 Pulsar measures 88 on power against 86 for Proton Series One Project Black. 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?
- Proton Series One Project Black 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?
- Proton Series One Project Black scores 90 for spin off its Raw carbon fiber face, against 88 for the Raw T700 carbon face on Ronbus R4 Pulsar. 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 6.5. Higher twist weight means the face rotates less when you miss the middle, and Ronbus R4 Pulsar carries the higher forgiveness score (82) as a result.
- Is the price difference worth it?
- Ronbus R4 Pulsar 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. Ronbus R4 Pulsar: 14 mm Thermoformed polypropylene with foam walls 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 5.5 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?
- Ronbus R4 Pulsar is the safer first paddle here: forgiveness 82 and sweet spot 84 mean fewer mishits while your contact point is still inconsistent. Ronbus R4 Pulsar rewards a repeatable swing and can feel unstable before that.
- Which is lighter in the hand?
- Ronbus R4 Pulsar at 8.1 oz against 8.3 oz. Static weight matters for arm fatigue and elbow comfort; swing weight (113 vs 117) is what you feel mid-rally.
- Is it worth upgrading from the Ronbus R4 Pulsar to the Proton Series One Project Black?
- Only if you need what it actually adds. Ronbus R4 Pulsar leads on maneuverability 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.
