I appreciate the confidence that some have in what I do, but I
certainly have a lot to learn about kites. My experience is that the
increase of speed is accompanied by an increase of pull. Philippe's
experience is different, but no less valid.

Usually, this is true. If the spreaders are made too short, then the
whole system changes (bridle pick points, angle of incidence, etc.)
which may affect stability negatively.
