I tend to play flat in the low half of my range and sharp in the high half.  Is there 
any reason to think that a mouthpiece swap would help?  I've been playing a large, deep cup mouthpiece for a couple of years.
If a mouthpiece is not going to help much, I may need to focus on the kind of practicing
I do.  Possibly more high register work?  I have been putting a lot of time on fourth
valve and low register practice the last 6 mos or so.
