Thanks for the advice. I ended up following Randy G's recommended modification since it was the easiest and I am lazy. I just got back from a weekend at Long Beach (Washington.) Winds were pretty brisk, but there were some relatively light air times too. What a difference a few centimeters makes! The kite was very well behaved in brisker winds (maybe due to decreased angle of incidence with the shortening of the upper outhaul), but it really shone as the winds dropped. Still can't do a Taz Machine with any consistency
, but pretty much everything else came easier than on any of my other R Sky kites. A real trick machine.
