Materials & core-spec scrutiny (faces, cores, edge tech)
Key Questions
What did the KewCast 111 surface roughness test find about USAP-approved paddles?
The test evaluated 42 paddles and determined that only 2 met the required criteria for surface roughness.
What core materials are featured in the Ronbus Tenon R2 16mm paddle?
It uses a dual-density foam core with measured specs including SW 109.95, TW 6.6, and surface roughness of 5.60 µm.
How is the Selkirk Omni paddle constructed compared to the Boomstik?
The Omni uses an EPP+EVA core with adjustable weights and full-foam InfiniGrit, positioned as a control-friendly alternative in Selkirk LABS comparisons.
What lab performance data exists for polypropylene cores like the JOOLA 3S and Diadem BluCore?
Tests showed exit velocities of 40-43 MPH, spin rates from 1078-1299 RPM, and consistency standard deviations between 2.42-4.43.
What are the key specs of the Honolulu J6CR paddle?
It features a 16mm multi-density foam core, swing weight 114-120, twist weight 6.5-6.8, and a Crystal Blue Endurance Surface claiming around 2,091 RPM spin.
What technical differences are noted between Gen4 foam cores and traditional honeycomb cores?
Gen4 foam addresses EPP vs MPP materials, off-gassing, and core crushing issues, with concrete comparisons between models like Boomstik and OMNI.
What lab results were reported for the closeout STRKR+ thin paddle?
It recorded 40.89 MPH exit velocity, 1585 RPM spin, 2.62 SD consistency, 932 swing weight, and 28.9 twist weight.
Which paddles use multi-density or hybrid foam cores in recent releases?
Examples include the Honolulu J3CR and J6CR with multi-density foam, plus cross-shopped models like Coral Pro Hybrid and J2CR Crystal Blue.
