Selkirk Labs Project Boomstik ST Elongated 16mm Power Pickleball Paddle

Built around the explosive 16mm BoomCore, the Selkirk Labs Project Boomstik ST Elongated 16mm Pickleball Paddle brings new spin and control technology to one of our favorite power platforms. PureFoam and the EVA Power Ring deliver the fast rebound we expect on hard drives and attacking volleys, while new Sharktooth Groove Technology adds perimeter flex for more dwell, improved shot consistency, and feel on softer shots. The 16.5in x 7.45in elongated shape gives us extra reach and leverage, while the 5.8in extended handle provides plenty of room for two-handed backhands. This makes it a natural choice for players who like to attack from the baseline and finish points at the kitchen.

InfiniGrit Ultra adds 4x more friction for spin and 50x the texture additive of the original InfiniGrit surface, giving us more confidence when shaping topspin drives and dipping passing shots. The Adjustable MOI Tuning System also expands the sweet spot and lets us customize perimeter weighting by hand to dial in balance and stability. We still get the signature Boomstik power, but the added dwell and adjustability make that explosive response easier to manage when the point slows down.

+ Key Features
  • InfiniGrit Ultra Surface - Upgraded USAP-approved grit with 4x more friction for spin and 50x the texture additive of original InfiniGrit, helping aggressive drives dip and topspin serves kick through the court.
  • Sharktooth Groove Technology - The perimeter flex-groove encourages longer ball contact and better shot consistency, providing additional feel when redirecting pace, shaping drops, and controlling transition resets.
  • Adjustable MOI Tuning System - Hand-adjustable perimeter weighting expands the sweet spot and allows us to personalize balance and stability, which is particularly useful when dialing in the feel of a longer paddle.
  • 16mm BoomCore with EVA Power Ring - PureFoam and the surrounding EVA ring deliver a lively rebound for deep serves, heavy groundstrokes, and decisive overhead finishes.
  • Multistrata T700 Carbon Face - Three carbon layers create a responsive hitting surface beneath InfiniGrit Ultra, helping transfer energy efficiently during full swings and attacking volleys.

Expert Review
"The Elongated shape is where we'd go for reach and heavy attacking shots. What makes the ST interesting is the combination of that explosive BoomCore response with a flex-groove designed to give us a little more connection on resets."

Frequently Asked Questions

+ Q: How is the Boomstik ST Elongated different from the original Boomstik?
A: The ST introduces InfiniGrit Ultra with 4x more friction for spin and 50x the texture additive of original InfiniGrit, Sharktooth Groove Technology for added dwell and shot consistency, and an Adjustable MOI Tuning System that expands the sweet spot and allows personalized perimeter weighting. The 16mm BoomCore and elongated dimensions remain unchanged.
+ Q: Does the Boomstik ST Elongated still have the explosive power of the original?
A: It retains the original BoomCore construction, which combines PureFoam with an EVA Power Ring for a lively rebound. The ST upgrades are intended to improve spin, feel, shot consistency, and adjustability rather than replace its aggressive playing character.
+ Q: How does Sharktooth Groove Technology help with control?
A: The perimeter flex-groove is designed to allow the ball to remain on the face slightly longer during contact. That additional dwell helps improve shot consistency and can make it easier to soften the response on drops, blocks, and resets.
+ Q: Is the Boomstik ST Elongated better for singles or doubles?
A: It works for both, but its 16.5in length is especially attractive for singles players who value court coverage and leverage on drives. Aggressive doubles players who use reach to attack volleys and finish points can also benefit.
+ Q: Which Boomstik ST shape should I choose for power?
A: Both share the same 16mm BoomCore. The Elongated offers more reach and leverage for longer attacking swings, while the Widebody provides a larger hitting area that can help maintain aggressive counters when contact is less precise. Neither is automatically the better choice.
