i am a lazy man, and therefore i use alternates.

I disagree. I usually don't like to pull slides, either. But on our last community band concert, we had the Gillingham arrangement of "Be Thou My Vision," and the legato line of the bass in D minor, including a lot of D's C's and G's, played a better fluid legato by resetting slides and using alternate fingerings until the key change.
Like anything else, alternate fingerings and slide pullings are another tool in the tool box to be used on the occasion(s) as required.
Oh, yeah - high range intonation. I am lucky. In my matching mouthpieces to instruments, I have great intonation in the high range on my Besson with the Wick 1. The Miraphone, because of the changed geometry of the retrofit bell, the high range can be a little squirrley if I'm not careful, warmed up, and focused. But that says more about me, and not about the Curry 128D.
