I was sittin here, considering Charlie's advice on enlarging the throat on my Helleburg when I decided to do a bit of searching on the subject. I came up with a neat little link that provides an interesting read on the subject. Sure, it may have to do with trumpet mouthpieces in specific, but the info stays true for ours as well. Enjoy!
In case the link DOESN'T appear:
