IF you can replace 2 kites with a single aluula kite it might not be a bad deal.
e.g. if you now have a 10M single-strut kite for light wind/foiling and a 10m 3/5 strut kite for a directional/twintip which you can now replace with a single kite that performs just as good or even better....
Replacing your whole quiver with just Aluula kites makes less sense to me unless you have lots of money to throw around.
