I've heard a lot of good things about the GR trumpet mouthpieces. If I didn't like my Monette MF-II so much, I'd try one. I have played on all of the other mouthpieces in the poll and some others not listed, at one time or another. IMHO, Monette is far superior in design, light-years ahead of any mouthpiece I've ever played on in the last 35 years. As a matter of fact, Monette is making a custom mouthpiece for me right now. It will be similar to the one Maynard Ferguson plays on, an MF-II with a 19 throat. I can't wait to try it out! :)
