So....I thought I hated a rounder rim!
Always go towards flatter rims, but wow... recently been using a more of a rounded rim and my range sound articulation has improved so much!
Anybody else has similar findings?[/img] |

Where did you find the rounder rims? To my knowledge only the late Al Cass made perfectly round rims. Today about the only stock manufacturer of slightly more rounded rims seems to be Marcinkiewicz. And he should be applauded for this.
And while I am certain that the average flattish rim contour is the right choice for some trumpet players I'm even more sure that plenty other trumpet players are poorly served by these flat rims.
The lips will bend easily but they do not like to fold much. Couple this with the fairly sharp inner rim edges or "bite" long prevalent within the mouthpiece sales business and you have a recipe for disaster. It is bad enough that the inner rim edge is sharp. However for the receded jaw type trumpet player (which is most of us!) this fold happens right on the inner edge bite. Compounding each issue 10x over.
Enter Al Cass mouthpieces just after WWII. Al's perfect rim contour radius and well rounded bite were the preferred choice of most the heaviest brass players of the 1950's thru 70's.
Red Rodney,
Blue Mitchell,
Sweets Edison,
Snooky Young, and the
Whole 1972 brass section
To name only a few.
So yes! By all means try and get ahold of the Cass series. I believe that Al's oldest son Steve has some modern pieces duplicated. In fact I own a couple at least and these are the real deal.

I was playing GR Bergeron which is quite flat, now moved onto a Yamaha 11a4 which I know isn't that round ,but in comparison feels it.
I feel like my chops are now gripping the mouthpiece in stead of being flattened and spread! |

In my (limited) experience changin' rims can be dangerous. A flat rim can limit flexibility but adds power and precision to attacks. Changin' from a flat rim to a rounder one will immediately "open" your sound, double the volume, more resonance but it may be a short honeymoon and you can overplay if you're accustomed to flat rims and damage muscles in the medium/long term (days).

The most comfortable rim (for me) has to be the Monette B11/C11. Very round!!

There are 15 significant parameters in the rim design. Rounder or flatter, Rc. What about high point r0. There are so many variables that we use testing to determine the best rim for you. Often GR can hear exactly what parameters are not correct and recommend a better match or make something.
I know people keep talking comfort. Unless it's cutting, it is about the lip being free to vibrate. At time too flat can impinge the lip, too round can bruise. The best way is to find the rim for you.
We've done extensive rim blind testing. If one doesn't work we know just what to test next.

Turns out the Yamaha rim is very similar to a GR 64.
I couldn't be more pleased with the GR 64ms I'm now playing , I've been playing GR for years ,I'm so glad To finally found the rim that is helping my playing in every aspect. I thought the Bergeron rim was for me, but now looking back its was hindering my lip vibrations for sure.  |
