Thanks for dragging us back on topic! I do find overtones and altissimo easier on these reeds (sorry if I said it before). The low end of the other Légère reeds was problematic, but it may just be I've gotten better so the American Cut makes it easier is just my imagination.
Your conjecture could well be the explanation. You're right, it's not necessary, but I like it. You have to be careful to actually take the reed out the way they say and not as if it was the usual plastic thing where you pull the reed up. They are nearly the price of a ten pack of cane, so maybe you want to be protected!
I have no ide"a what they cost to make (mamybe a few cents?) but they last as long or longer than several canes, so I'm good with it. I really like the sound and the feel. I've been using nothing but for weeks, although I keepo trying canes from time to time.Legere are having our pants down at £30 a pop
