@ Peter Frank, as I am aware you are more or less considered as a specialist here, Ithe "story " of getting pulled off the board, I do not entirely agree with, as you also will be aware of, in waveriding you do not like to fly overpowered, it is more fun to change your kite instead of depowering it.
So I personally do not see why I would be pulled away if I fly the right size of kite.
As I tried to explain - there is a reason why wavekites in generel (for the average weight rider that is) are not low end kites.
You dont want to ride too powered in waves, I agree.
But low end kites has less range than a tad bigger not-low end kites, thats a fact.
(I wont go into the physichs now, but many/most know or have experienced this)
So if you take a smaller kite, so you are powered "okay" when going straight out - then this kite will be much easier overpowered when going down a huge waveface with speed
OR, if you fly the kite down deep in or across the window - you have to follow the pull of the kite somewhat (with smaller kites / heavy winds especially), instead of having full freedom to make a curve or line "whereever" you want on the wave - because you dont have to follow the "string".
So the low end kite will generate huge amounts of more power when speeded up - that goes both for riding down wavefaces, as for flying the kite around in the window
The tad bigger kite with more range, can be depowered more, and has a softer way of pulling you, so even though these the 2 different kites gets you upwind the very same (same pull when going straight), you will be able to handle more speed much easier with the "depower" kite (the non-low end kite a tad bigger).
This is why wavekites are typically designed with bigger windrange and less low end
For freestyle or freeride you dont need this feature - but will usually prefer a bit or a lot more low end instead, so you can use a smaller kite that has a more steady pull, so this is the reason why there is a difference in these kite types, as simple as that
Of course there are huge personal likings and differences, so some light riders like low end kites in waves, and some heavy riders like depower kites - and personal riding style can also influence - but in general above is why wavekites are chosen/designed with more range and less low end, than other kites.
There is a limit, so too much depower is also bad (for the light riders too).
And as stated often, the heavier the rider, the more low end is preferred - to "feel right"
We are NOT talking about a similar kite size here, just different low end or non-low end kites with the same pull, choosing different sizes of course - this is important in order to understand this topic fully
