Messed up again, foilholio? I'm afraid you are the local fool here
I wrote earlier race foil generates its power when given time to get its speed up, before that it does not pull very much. Small sizes generate power faster than bigger ones, because their inertia is relatively smaller.

This is foilholios biggest concern about the new race kite... For real, this kite has 62 cells, meaning it has 124 panels and 61 ribs, tens of diagonal ribs, 186 pieces of spanwise straps, 9 air intakes with valves, 61 plastic rod LE stiffeners, quite complex (even though well designed) bridle... Lightest possible weight seems not to be very high in design requirements list.
I don't know the exact weight of J7, but J6 was a bit heavier than J5. Air inside 11m kite weights near 2kg, kite itself about 2,5kg, perhaps close to 3kg because of the high cell count. So total weight is more than in similar sized LEI. However high L/D ratio is much more essential than agility with these kites. I wouldn't say 11m race foil is very slow, but of course it is slower to turn and accelerate than same sized LEI, these have also much lower AR (shorter wingspan). For its designed use as a race kite there is plenty of time to collect the speed, it is very much a park-and-ride sport.
Jokers are kites in which designer has done his work, I don't see much to add or criticize
