I have used a 12m Switchblade 2 in Melbourne for almost a year and have been out in 14knots up to about 28knots ( 28 was a bit much but manageable ).
Originally I planned on buying a second smaller kite but have found no need.
Very happy about that

Not so happy about the Cabrinha quality

ie :
Have now broken 2 trim straps (strap above bar for adjusting power )

in 9 months ( yes i avoid putting my bar in the sand )
One leaking bladder from new

First 12m Switchblade ripped in half on very first impact with water on second day of use ( was repaired under warranty but not replaced )
Purchased a new one ( as I was told it may take weeks to be repaired or replaced , it took 6 weeks ) and did not want to miss the summer.
Two snapped Lines
One broken pulley
Not every one has had issues with cabrinha maybe I got 2 dud kites but quality issues aside I love the way the kite works.
