Selkirk Labs Project Boomstik Elongated 16 verdict
The highest measured power in the database, and the twist weight (7.2) to back it up. The MOI tuning system lets you dial the balance, but nothing turns a 118 swing weight into a fast-hands paddle.
Six Zero Sapphire 16 verdict
Six Zero's standard-shape Gen 3 build. It trades the Coral Pro's reach for a wider face, and the result is one of the most forgiving control paddles in the $200 bracket.

- Six Zero Sapphire 16, at 106 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 Sapphire 16?
- Selkirk Labs Project Boomstik Elongated 16 measures 95 on power against 80 for Six Zero Sapphire 16. 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?

- 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 91 for the Toray T700 raw carbon face on Six Zero Sapphire 16. In practice a 0-point gap is small enough that technique matters more.
- Which is more forgiving on off-center hits?
- Selkirk Labs Project Boomstik Elongated 16, with 7.2 twist weight against 6.7. Higher twist weight means the face rotates less when you miss the middle, and Selkirk Labs Project Boomstik Elongated 16 carries the higher forgiveness score (88) as a result.

- Which is better for a two-handed backhand?
- Selkirk Labs Project Boomstik Elongated 16, at 5.8 in of handle against 5 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 is lighter in the hand?
- Six Zero Sapphire 16 at 8.1 oz against 8.25 oz. Static weight matters for arm fatigue and elbow comfort; swing weight (106 vs 118) is what you feel mid-rally.
- Is it worth upgrading from the Six Zero Sapphire 16 to the Selkirk Labs Project Boomstik Elongated 16?
- Only if you need what it actually adds. Selkirk Labs Project Boomstik Elongated 16 leads on pop by 18 points; everything else is within 18 points. At $332.99 vs $190, the money is better spent elsewhere unless that one trait is your weak spot.
