Hi there !
I had to answer this one...
Skoop(1) has more low end than Skoop2, but not quite the same windrange.
Skoop2 turns a bit faster than the Skoop, and has amazing windrange - but not much low end.
Both kites are fully front line flyers, and will slow down or stall if you pull the rear lines too much (just like an Airblast will).
Skoop3 can be flown with lots of pull on the rear lines, without stalling at all.
And the windrange seems very similar, because of the reduced drag with the narrow Leading Edge.
It has more power and hangtime than the Skoop(1), especially in the jumps, as it does not lose power when turned, because of the Wing Span Line
The low end grunt is about the same - but a tad better, than the Skoop(1), as you can pull more on the rear lines.
And it turns faster than both the Skoop(1) and 2, for sure
And the AR is slightly lower for the Skoop3, than Skoop 1 and 2 - but it is still a really fast kite that flies to the edge when you want it to.
These are the general differences amongst these 3 kites.
