Diadem Edge 18K V2 verdict

Diadem's 18K weave measures at the top end for spin without the harsh feedback most thermoformed elongated paddles carry. It is the balanced option in a category full of specialists.

Proton Series One Project Black verdict

A thermoformed unibody built around stability. The foam walls push twist weight to the top of our scored range, which is why off-center drives still land deep.
