I had a very old Otto Link Ebonite mouthpiece (over forty years old) that I recently dropped very unfortunately and has been unusable since. I tried to get a recent Otto Link 7* ebonite mouthpiece. Unfortunately, the current production is quite defective and very poorly finished, and the mouthpieces are practically unplayable. So I tried a Vandoren V16 mouthpiece, first in the 8* version (very satisfactory but a bit tiring for me), and I ordered a 7* which is quite excellent. I just ordered, still in Vandoren V16, a 6* for classical music which I also find quite excellent. So a big bravo.
