Love my heritage mouthpiece - Wick 3B. I get a much nicer sound out of it than any other mouthpiece I have played on. Also, because I have a fixed ceramic brace, the wide rim spreads the pressure much more easily. If I try and play on a 'normal' wick mouthpiece then the cuts, ulcers and splits I get compared to the heritage are not pretty. I tried to go back to a normal one when my front teeth shifted because I started to loose air out the side of my face. However, as my front teeth are pretty straight now that (thankfully) seems to have stopped.
Played on a heritage 4 for over a year but have now gone back to my Wick Webster 3 as it is more comfortable to play on.
