Mark, you won't be echoing me. I use the high rage (Gs above C up to double high C) a lot in my every day (non big band) playing, even on flugelhorn. It has it's place, but can add so much excitement and dynamic to the music. I ended a ballad the other day on the Bb below (1 whole step) double high C. It sounded like angels singing. The crowd just went Oh wow!
