Jet is a dedicated race kite. The bigger jekylls were..well. just big jekylls... The Jet has a even more effective Proj.Area.
Jet has been stripped of onepump and alot of dacron to save weight, even the backlines on the bar are less thick to minimise drag.
Thekiteboardermag tested it as "Pros:
Amazing upwind performance, even in very light wind.
Very stable, even in big lulls.
Very good low end power.
The Jet demands more attention from the rider to get the best performance.
Some riders may be turned off by the lack of a single point inflation system. "
The latter is a kind of non-issue, considering only diehard low-wind fans and racers will use this kite.
Also, the attention needed is because it is such a high AR kite, which you WANT in racing.
