I don't get it. It's all about loading right? For a given kite size and wind speed, whether it's a 75kg kiter that needs to aggressively edge or a big poluka that doesn't need to edge as much in order to keep things going right - the loading is similar.... No?
It all comes back to correct kite and board sizing for a given rider weight and wind speed doesn't it?
I suspect this thread is a non-argument in disguise...
No. It's about inertia...
Correct board and kite is fine
once you're up and planing, but big guys - properly big guys, not 90kg girly men

- can over-load the kite much more easily for longer (getting dragging around in water, for example) and the instantaneously peak loads can be pretty high...
Think about a simple example - a gust hits 2 kiters of different weight, on the same kite. Skinny gets lobbed, fatty stays in place - which kite is suffering under more load?
