I think if there were more engineers / scientists in the sport it would look very different, we would probably be a few years ahead in the designs. People without that background have to learn using trial and error what is obvious for someone with that education.
For example, take a look at adding dashes for kites.
We only see that on inflateables in 2008. Flysurfer, the super duper technology gurus with massive aeronautic background from designing paragliders and sail, had it in 2004. Same with many other things, like the shape of the first crossbow that was shockingly similar to the very efficient Psycho, and you can go on and on.
Now imaging if the tube companies introduced those features at the same time flysurfer did. My guess is that things would look different now after a few years of fine tuning.
Not that I have anything against the gear you can get today which is awesome, I just think we could have had it much earlier, or maybe its about time that
FLYSURFER BUILD A DAMN INFLATEABLE
Of course there is no substitute to hands on experience and good guts feeling that also comes from experience.
