Mouthpiece recommendation for EEb Tuba

[SouthernOhio53]

If any of you play an EEb Tuba, like the Besson 983 as your only instrument, what mouthpiece do you use when playing in large ensembles with BAT CC tubas?

I have had the privilege of borrowing a Besson 983 from one of the DMA euphonium students at Michigan State over the last few months to play in a brass band of which we are both members. I really like the way the Denis Wick 3l heritage plays in the 983, and I think that it puts out plenty of sound with this setup. You may try a 2l or 1l to give it a little more girth in the low register but I don’t find that necessary.

I've been using a Warburton T.G. 4, the original "The Grail" model.
