Otto Link Tone Edge Tenor 7

I'm not a professional sax player, so take my opinion just as that.
Coming from alto playing, my transition to tenor was with this mouthpiece.
At first I found it dificcult due to the larger air column. Once my diafragm got used to it, I found the mouthpiece quite accomodating to my developing embrochure.
I tend to find the control over the lower octave more demanding that the upper ones.
The sound is bright but not so much as other models I have tried, like Aizen, f. e.
I'm working now in my altissimos and having a hard time with it.
The mouthpiece is not to blame though.
I will stick to it for the time beeing
