Thank you very much for your comments and advice. I fully agree with you there!
I ask because with every NEW kite the wind range is always specified by the manufacturer. (I know it is a recommendation!)
I just bought a nice OLD set from 2009 and just wanted to complete the data (size, weight, frame etc.). Could have been that someone with similar kites wrote down something like that.
"develop your own feel" it takes time, be patient, enjoy the journey of exploration
comparisons are great fun if you have a partner, just change one variable and see how it feels "better or worse:" WHY?
A kite club starts by you showing up to the same spot repeatedly and sharing your passion with spectators
