"since the wind range overlap is so broad"
Indeed!!
Here is my experience with it .....
Up at WSIKF one day, John had all 3 versions of the Djinn out for people to try. The std version was always in someone's hands, so John suggested I try the midvent. I put it up, made a minor adjustment to the top lines and flew a bit. Felt good, but in those light winds, nothing stood out to me as spectacular. After a bit I put it down, told him very nice, and was waiting for the std to come open. Then he says - "Try the full vent." Now I'm skeptical, these winds wouldn't be enough to fly what I use regularly, so I look at him and he says - "Just try it." So I launch it, and am amazed that it can even fly in these winds! Then a strange thing happens - pretty soon I'm leading a line of fliers. Now this may not seem out of the ordinary, as I do this fairly regularly, BUT I"M DOING IT WITH THE FULL VENT!! Any moment, I'm expecting the mid and/or std to run me over!! NOT! Led for quite a bit, put it down, and just shook my head!! Did I just see what I thought I saw??
OVERLAP? - INDEED!!
