Tony,
Thanks, great advice. I've been trying to play very soft scales and sustain the upper register routine for some time now. I guess I just have to be more patient.
It's just frustrating because since I was 17 (more than a couple of years ago

) I've had a solid G, and the rest are just squeaks. And I can't remember doing this before to get that range. I'm kinda stuck...and I'm afraid to ask, but do some players just 'top out'?
Peace,
Andrew
