Many thanks for the great mouthpiece. It was immediately very comfortable for me, and works beautifully on my saxello. The low register speaks effortlessly and feels totally connected. I love it! I think the Open Sky 2 is a bit more powerful and has a sweeter/rounder tone that is more consistent from top to bottom than my (deleted). I was surprised at how well the included ligature works. I own a similar Brancher ligature which has a longer contact plate. Yours fits and sounds better.The OS2 is a fantastic piece of equipment; exactly what I was hoping for.
