Bindings Advice Sought

The last time I skied, I caught an edge, my bindings didn't release, and
tore a knee cartilage. I can't recall these bindings (Salmon S850 with ~
15 days of use) releasing -- ever -- except in "yard sale" falls. After
several years off skis, my knee has healed to the point that I'm ready
to try skiing again, but I don't want to fzck my knee completely, and
wonder what I should do to make sure my bindings will release safely.

When the bindings were set up, the ski shop asked me for weight, height
and skiing ability, and set the bindings at "7". Given that they never
released, I wonder if they should be set up lighter? And how do I make
sure they're set low enough that I don't reinjure my knee, but don't
release in normal skiing?

Finally, over the years I've heard many people condemn Salomons for
being unforgiving. Is that an old wives tale, or are there safer
bindings I should consider (whether newer Salomons or other make)?

Thanks,
