Nice. I bought mine second hand so I think it is the "regular" weight - which is already crazy light. Maybe the lightest kites per m2?
I sold my 6m peak 5 as I felt that this kite covers its range. What I said after the first couple of outings still holds - it is an impressively quick and agile kite which is at least as fast as the 6m peak and I think that the useable top end is at least as good.
I cannot comment on relaunch yet as I have not properly crashed it.
The main weak point for me is not much power in the loops for starting in light winds. At the absolute bottom end I am not sure that I am better than with the 6m peak. I have not tried tweaking the bridle or adding longer lines, and tbh I did have longer lines on my peak (~25m).
If I could make a wish list for the hysper v3 I'd try to improve the flapping at the wing tips when the wingtip is depowered (e.g. in tight turns). I think a less square shape would probably behave better, but perhaps this will sacrifice some of the fast turning? I have experimented with adding nylon filaments to the outer cells (easy to form a pocket by sewing together the loose edges where cells meet - I can take a photo if there is interest). The latest mod I'm testing is a bit more radical - a 2mm carbon fiber rod inside a 1cm diameter soft foam rod, inserted into a pocket sewn into the wide wingtips (a bit like the spars in a Peter-lynn Arc, but much more flexible). This keeps the wingtips in much better shape, but I suspect it will cause trouble with bridle tangles, so I might not keep them. Another minor issue in the design is the white ribs to which the lower bridle lines attach. These are very light so you notice that they are often not under tension and flap a lot.
Overall I am impressed with this kite, which is the biggest kite I have tried which has the fun small-kite feeling, and I look forward to seeing whatever else sky country have in store. I'd be interested to try a 6m. I am not sure that I would necessarily like this model in the 4m size - I get the impression from what I read that it is a bit too fast for my taste.
