Well, they certainly were not marketed that way or advertised as such. When I bought a Radar Senate years ago my local ski shop was extolling the virtues of the feather frame to me, and I am 6'1" and 220. Never have I seen anything in the literature, brochures, or on the Radar web site, saying "for women, kids, and people under xx lbs. Not for big skiers"
I know the difference in the binding levels, having used Profiles, Wileys, Animals etc, all on plates. All I am saying is that in my opinion, for a relatively small market like waterskiing, bindings should be interchangeable, without having to break out the drill.
