Because my opinions are seen as biased, I decided to post some technical info on the SIGMA and Geo-tech, so that it might help explain why these kites fly so well.
THE SIGMA OUTLINE.
The core concept of NAISH's SIGMA kites is a radically re-shaped leading edge that moves much of the center canopy area behind the tow points. The result is a kite that delivers significant performance improvements in 4 key areas. Overall stability, bar pressure and feel, turning and relaunch.
The SIGMA design produces a balanced, linear power band combined with bar pressure that remains light but steady through a wide range of trim angles, creating a nearly perfect feedback loop between rider and kite.
With the SIGMA design the lifting surface remains in a safe neutral zone behind the tow point even at extreme de-power. This minimizes the movement of the center of effort, resulting in a very even bar pressure regardless of the kites flying position.
The SIGMA leading edge enables the rider to turn the kite at any speed with absolute control. The SIGMA leading edge produces a hinge point at the center of the kite. Unlike conventional kites that use a maximum of 30% of the kite area to generate turning forces, the SIGMA clearly twists from the center to produce a highly effective turning shape (comprised of nearly 50% of the total kite area) that responds more quickly and accurately to rider input.
The SIGMA kite offers the easiest relaunch in Kiteboarding history. This is due to the greatly reduced contact with the water from the SIGMA shape, and how the kite is able to pivot off either shoulder for relaunch with very little rider input to the lines.
GEO-TECH
By incorporating straight segments in the leading edge from strut to strut, canopy tension is kept constant. Wind pressure in not necessary to maintain the canopy profile, and at low angles of attack GEO-TECH keeps the canopy from collapsing. By Maintaining a constant aerodynamic leading edge GEO-TECH provides a wrinkle free canopy, large de-power range, and stability at broad angles of attack where historically kites with large de-power range have experienced distortion.
Combined with the SIGMA shape, GEO-TECH creates the most precise and controllable kites ever, which maintain this feeling and control through an amazing broad wind range.
By running straight leading edge segments from strut to strut, GEO-TECH is able to maintain tension in the canopy between the struts. This allows the struts to both actively maintain the tension and to more accurately shape the canopy profile from the leading edge to the trailing edge.

Hoping to get a ride today at lunch at fisherman's beach (brown water) if the NNE comes up enough.
