Let me elaborate a little:

With high G we get:

- power depends on G^2
- the above gives us more power with less mass
- higher speeds lets you cover more air area with the same wing
- changing effective G is an efficient means of depower giving an immence depower
- as the kites are already flying fast, dealing with extreme winds is «built in»

But, it also means

- tether drag becomes a dominant factor
- larger forces need to be soaked up by a kite on a smaller area
- a kite can only have a biggest G and still be flyable (pushing to rigid wing vs soft kites)
- high AR wings stall really easily at a lower AoA
- the power effect of gravity increases with speed and mass (power = speed x mass x 9.81), leading to uneven power generation

The question I am wondering is where the balance is between pros and cons. At one end of the scale we have «single skins» that fly with low G but have a huge area at close to zero mass. At the other end, Kitemill/Makani/Ampyx/(most other actors) going for rather heavy high G designs. I think this might be perhaps the most important question for AWE, and a question where there seems to be no concensus at the moment

My worry is that focusing only on the first order approximation that high G is better for power, we might be excluding the most useful kite designs…
