Aero 12 / 14
The Aero steers much quicker. The Aero design is leaps ahead of the
arx. More stable. Stable, predictable wave riding kite. Once you
ride em, you will notice the huge difference in turning, and
understand what the improvement is over the arx.
The 10 - 16 are good kites. The aero is more predictable like a 2
line. The X2 is an inflatable that flys like a foil, a great design
for the bigger sizes. A 16 X2 turns faster than a 11.5 ar5 and arx.
Maximum hight.. go for an X2. A slower kite for the windier
days...go for an aero. Trickstyle...go for Lou's Virus or a CO2.
Stop the windsurfer tech shop talk and ride.
Overall, They all are DA BOMB.
