Very helpful thread - thanks kemp90 for starting it, hope it is ok to add to it.

I am 60kg & am looking for 2 kites for 10-25knot range. I have had 3 sessions on a Double Agent w 40cm mast & had a couple of 30metre heelside foil runs & heel toe turns but my 2012 Cabrinha Vectors 7/9/12 are often either overpowered or falling out of the sky so I am rigging to be overpowered (& fully de powering when on foil).
I am wondering if Airush Ultra 5m & 7/8/9m (or Bandit or Mono or Notus Air) might be better to learn with? With a spare set of line extensions to extend the range of the kite I am using.
Any advice much appreciated on what you would recommend for my weight, wind range (not too windy or fast) & skilllevel
a. which kite
b. what sizes
c. whether I should persevere w the Vectors a bit longer
d. Who demos & sells Ultra & Notus Air in Sydney
