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 Infinity Ruby 16 verdict
The edgeless Ruby. Removing the edge guard adds face area and twist weight (7.0) to a paddle that already had one of the most durable spin surfaces in the sport.
The verdict
Measured on the same 15-trait test, the clearest separation is power: Selkirk Labs Project Boomstik Elongated 16 scores 95 against 88 for Six Zero Infinity Ruby 16 — a 7-point gap.

- Which is better for a two-handed backhand?
