Have you flown a kite with the TWS ?
Yes, I had a C21 Extreme
Have you designed a kite or your own ?
Yes, though nothing groundbreaking. I've made several dozen kites over the years for my own amusement.
And or some alternative weighting system ?
only if you count substituting an appropriately sized pebble when I lost the one for my Cesium.
I'm just wondering what you think qualifies you to make such a statement ?
just my opinion. I am allowed opinions here, aren't I?
