thank you for making that distinction, it is very true that bridle and canopy shape / design have a lot to do with the effectiveness of double center line "flag out" or disable systems.
as for the actual drift launch, i have experience drifting many different kites, and as with almost everything in this sport some shapes / kites consistently do better (or worse) than others. so far i have found it is possible with all, and have also found that problems (of all so far mentioned natures) are also possible with all.
ronnie: thats also a very good comment about how instructional videos should explain things that can potentially go wrong (and how to see it coming, and deal with it) that type of things is rarely covered.
