Selkirk Labs Project Boomstik Elongated 16 verdict
The highest power score 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.
