I don't know about a chart comparing funnels to bowls, but there is the great Dwerden.com chart

You might want to check out an MF3 or PT-50 if you want a slightly larger funnel cup.

Paul Sidey's SSH Original or Classic sounds like what you're looking for.

They are quite nice.

They're made of stainless steel and available in American or Euro shank as well.

I have an SSH original and a Curry 130DH - both have slightly larger rim diameters than a Conn and slightly flatter rims and maybe larger backbores(?). If you feel the Conn is holding you back, then maybe they would help. Neither suits my current tastes, so PM if interested. I still like this chart, as far as charts go: http://www.militarymusician.com/xcart/p ... ?pageid=12

I personally believe the standard(120) Helleberg is an excellent mouthpiece. I will admit to being curious who those three "heavy-hitter" tuba players are, however.

"Canadian Brass/Arnold Jacobs" MP is also pretty big, too.

The Marcinkiewicz H-series 'pieces are Helleberg-types, as I recall -- H1 being the deepest, and H4 the shallowest. ID is around 1.325".

Yes, this is good. My CH H2 is amazing and an atom bomb when combined with a beefy horn. They are pretty wide, though. I wouldn't call it "one-size-larger".

Mount St. Hellensberg!?

If getting more air through the mouthpiece is an issue, try a Wick 1L -- it is one of the deepest true funnels made.

Loud's LM-3 is probably the largest funnel available in a non-custom mpc. There are a couple of screw rims available as well with that model. I have one and it is significantly larger than a PT-50.

If you want a really deep funnel then either of the Dr. Young mpc's will do. I personally like the older Reynolds version but it does seem to induce a secondary buzz in both the 1291 and the large Rudy I'm currently using. As Mrs. Lincoln said: "Other than that I enjoyed the play."

Don't you wish everyone had the enthusiasm for a mouthpiece that "iiipopes" has for the Wick 1L?

Thanks. It is a fine mouthpiece. It isn't for every application. For example, as fine as my Wick 1 is for my Besson, because of it having inherently more overtones and the resistance of a comp valve block, I ended up needing a 3rd lung myself to use a 1L on the 186. So I had to discontinue using the Wick 1L on the 186 and go to the Curry, as for my 186 with its retrofit St Pete bell it is darker than most, and I needed a smaller throat with a little bit of curve at the bottom of the funnel to help me regulate and conserve air support.

The reason I mention it is because it is such a fine mouthpiece that is too often written off as just a brass banding mouthpiece, rather than what it is: a true deep Helleberg style mouthpiece. It sounds best on any tuba that is either inherently bright or has a lot of inherent resistance. I ended up giving my Wick 1L to a friend who plays a Holton (probably made by Yammy) 3/4 that is about 25 years old, and he sounds great on it.

For those who have the lungs to support its 8.43 mm throat, it should be on the short list of anyone wanting a darker, broader, bigger tone, all the hype about heavy weight and stainless steel to the contrary notwithstanding.
