I agree fully with your observations here
Would just add a few comments not mentioned :
The Furia is by far the fastest turning kite of the 3 - Furia, Nova3, and ENova2.
But one VERY important difference between the Furia and the Nova3/ENova2 is the depower stroke
It is much shorter on the last ones, and still with (selectable) low or perfect bar pressure.
So you can depower very fast, and dont need the trimstrap for anything but unhooked trim or walking on the beach maybe - no more "long arms" needed !
Think I've mentioned it in another post - but could not find it
I love that - not having to adjust the trim when riding hooked almost no matter what wind, it always "fits" like it is, and you get the "feel" of the kite on your backbone, and can really get the highest performance out of your kite
(not possible if you constantly change the trim, no matter what kite...)
The only downside is, that for the Nova3 it is more difficult for beginners (IMO), as they can easily sheet too much out and lose power, or pull too much so it does not perform max.
This will lead many to immediately think it has less grunt - but it has MUCH more grunt than the other kites, so just a matter of learning, and when you have - it is a powerhouse
Whereas the ENova2 is much easier to find the "sweetspot" regarding bar position, and extremely suited for beginners also.
Although, I use the ENova2 mostly myself (and an 11m2 Nova3 for real lightwind conditions) - because I find it has so excellent waveriding/upwind/hangtime features - all in one !
At least my own observations so far...
