My daughter has been expressing interest she is 42kg wringing wet so wondering what might be a good kite.

im thinking I wouldn't be taking her out in greater than 15 knots (ball park) so have pretty small wind range 10-15 I guess.

Need a kite that would launch and fly well in that wind zone but guessing 6-9 m. Would be as big as should go?

any thought?

ps was looking at a slingshot rally 6m
And maybe my 9 m rpm, but it doesn't seem to fly great under 15 knotts
