Six Zero's answer to the hybrid trend, and the most balanced paddle in our 2026 database. Very few weaknesses at this price.

- Which one is faster at the kitchen line?
- Six Zero Ruby, at 114 kg·cm² swing weight against 118 for Selkirk Labs Project Boomstik Elongated 16. Lower swing weight is the single best predictor of hand speed in fast exchanges.
- Which paddle has more power, the Selkirk Labs Project Boomstik Elongated 16 or the Six Zero Ruby?
- Selkirk Labs Project Boomstik Elongated 16 scores 95 for power against 85 for Six Zero Ruby. That comes from a 16 mm BoomCore PureFoam with EVA Power Ring core swinging at 118 kg·cm² — mass behind the ball, not face material.
- Which one gives more control and touch?
- Six Zero Ruby at 86 versus 84. 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?
- Selkirk Labs Project Boomstik Elongated 16 scores 91 for spin off its Multistrata T700 carbon with InfiniGrit face, against 88 for the Raw T700 carbon face on Six Zero Ruby. In practice a 3-point gap is small enough that technique matters more.
- Which is more forgiving on off-center hits?
- Selkirk Labs Project Boomstik Elongated 16, with the higher forgiveness score (88 vs 81). Its 7.2 twist weight against 6.6 is what drives it — higher twist weight means the face rotates less when you miss the middle.
- Is the price difference worth it?
- Six Zero Ruby costs $160, $172.99 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?
- Selkirk Labs Project Boomstik Elongated 16: 16 mm BoomCore PureFoam with EVA Power Ring core with a Multistrata T700 carbon with InfiniGrit face. Six Zero Ruby: 16 mm Thermoformed polymer core with a Raw T700 carbon face.
- Which is better for a two-handed backhand?
- Selkirk Labs Project Boomstik Elongated 16, at 5.8 in of handle against 5.4 in. Anything under 5.25 in forces you to choke the bottom hand onto the face bevel, which Selkirk Labs Project Boomstik Elongated 16 avoids.
- Which one is better for beginners?
- Selkirk Labs Project Boomstik Elongated 16 is the safer first paddle here: forgiveness 88 and sweet spot 89 mean fewer mishits while your contact point is still inconsistent. Six Zero Ruby rewards a repeatable swing and can feel less stable before that.
- Which is lighter in the hand?
- Six Zero Ruby at 8.2 oz against 8.25 oz. Static weight matters for arm fatigue and elbow comfort; swing weight (114 vs 118) is what you feel mid-rally.
- Is it worth upgrading from the Six Zero Ruby to the Selkirk Labs Project Boomstik Elongated 16?
- Only if you need what it actually adds. Selkirk Labs Project Boomstik Elongated 16 leads on plow through by 13 points; everything else is within 12 points. At $332.99 vs $160, the money is better spent elsewhere unless that one trait is your weak spot.
