Just to say; absolute revelation!!!
The search for the ‘perfect’ soprano cornet mouthpiece is a thankless task. You usually have to sacrifice range for tone or vice-versa.
I am no top section player, but this piece (Sparx 4E) is perfect in my eyes as it achieves both. I can only wonder what a better player can do with this piece of witchcraft you have created 😁
