I used the Cult 9M for about 2 weeks in everything from 10 knots to 22-28 knots-AMAZING range. Used it on a twin tip and various directionals and surfboard unstrapped.
I have no association with any manufacturer. Own Naish, Best and North kites.
I found the kite to be very smooth and with a huge wind range-bar pressure, whilst lighter than many other kites, is still very positive.
The kite is super responsive. Waveriding it hangs of the lines very nicely and just floats back in the window as you depower the kite and surf the wave. Super stable kite.
Relaunches like it's on steroids-almost auto re-launch-bloody great when you drop it in the waves

.
Bar is super simple-with an easy use (although a little far away to reach) depower system.
Only negatives:
1. relaunch on the beach in light wind.
2. some leach flutter
3. distance of depower from the bar-hard to reach
If I had the $ I'd buy one in a heartbeat!
