Tyronsea 360 is a good board to learn on. I sailed one for a few years. We all learned on boards like this.
I would disagree, agree and agree with you.

That's a good example of survivorship bias. A million of this kind of board were sold. Maybe a tenth stuck to it. We're what's left of the tenth after kites/wings/other interests pared the count.
I remember running clinics with boards like this. If, by the end of the day, someone could actually stay on long enough to sail out and back, we'd all applaud. Now on modern gear, I can get a teenager to do that in twenty minutes and not get their hair wet.
en.wikipedia.org/wiki/Survivorship_bias"This hypothetical pattern of damage of surviving aircraft shows locations where they can sustain damage and still return home. If the aircraft was reinforced in the most commonly hit areas, this would be a result of survivorship bias because crucial data from fatally damaged planes was being ignored; those hit in other places did not survive."
