That old flick trick won't work with Legere unfortunately. Must have been stored bent. Heat might work. Submerse in boiling water for 15 seconds or so, then pop into a reed guard to cool flat. This will temporarily make the reed softer, but it will go back to normal strength in a few days. Alternatively, if the reed is less than 6 months old and you have your receipt, you can do a free exchange through the Legere website.
Personally, I've never cared much for Legere on clarinet or sax, except on low voices like bari and bass. Even then, the high register is buzzy and unstable. Cane is still king for me.
