If I understand it correctly:
a small kite with short lines = small drag but a bit faster in the turns,than with long lines
a small kite with long lines = slightly better drag but slightly slower in the turns, than with short lines
a greater kite with short lines = greater drag and a bit faster in the turns, than with long lines
a greater kite with longer lines = slightly greater drag but slightly slower in the turns, than with short lines
so if the wind drops, I should choose a bigger kite, with same lines, rather than install longer line at the kite i am using,
to achieve the same speed without losing control properties
After I wrote this, I better understand why I am a bit confused
please tell me if I got it wrong

by the way it's nice to get good and quick response, thanks
