The JOJO Rage is my favourite Soft-Surf-kite.
It is based on the design of the JOJO-RM.
They changed some smaller details, for example the angle of air attack to make it more stable and less aggrssive than the RM and I think they did a good job.
I tried the Rage in CAP VERDE. It is very powerful, stable and though the AR is very high, has a good turnrate. The RAGE is normaly used as a 2-liner. It comes with a third safety line to full stall the kite and a depower system that changes the profile. To have a high turn rate they use a power steering system that automatically activates flaps on the side you want to turn to. The leading edge is closed and has 6 intake valves. Two of the inlet valves can be turned inside out to make it easier to deflate the kite. There are 2 bigger and 2 smaller zippers to support deflation and to take out sand and dirt.
The quality of this kite is the highest standard. Must be why JOJO also manufactures paragliders and parachutes.
This kite is a really good choice and after a modification to use it with the SPIDER bar it is a dream.
But I can only tell you my impressions.
