Yeah, it took a little to adjust too, but I really like the mouthpiece too. My 3 main chromatics are an SCX64, an old style Super 64, and now the Meisterklasse. The Super 64 is my least favorite for tongue blocking - the edges of the holes aren't too smooth, but it's OK. The SCX is great, and the Meisterklasse is just as comfortable if not better, but feels much different. It seems like it's own thing.
The only thing about it I don't like is those 2 missing holes that I get in a 64. I can still play the same songs, but have to change it up so I don't try to blow into holes that aren't there, which I did several times when I first got it.
