Does anyone use a tug tow hook that releases automatically whenglider kites?

Dan, that might work if the towplane's attitude was constant. However, during a kiting event, the towplane is being pitched nose down, so the hitch would not likely get activated, as the hitch to surrounding structure angle may not change. I wish it could be that simple, but it isn't. See the previous post about a kiting even where the glider was still in sight in the mirror, even though the towplane was significantly nose down.
