Nigel's revolutionary contoured foam core blades are produced by Point65 in two versions, "AIR" in carbon, and "GS" in fiberglass. With powerful drive, reduced flutter, these blades are great for precision maneuvering.
Both versions are the same size and shape. Both come with a foam core construction blade and carbon shaft. The "AIR" is amazingly lightweight, with carbon blade and carbon shaft.
The "GS" yellow blade fiberglass version is still very lightweight, with its all-carbon shaft, but a little heavier overall than the "AIR".
Note: Nigel's earlier paddle designs, the Hi-Pro and Sports-Pro are no longer in production, although you may still see them in use. They were a significant step forward in design from what was available before their release, even though they've since been superseded by the AIR and GS.
