Some do, in-fact lots do but not all.
My old section at Fodens used to play on 24AW, 24AW, Bach 18, Bach 7
Some of the finest BBb players also used 24AWs to get the mellifluous BBb pedal sound required in the top bands (like dry ice falling off the stage was the way one top player described it to me).
Many use Wick 2s, more are starting to use the 3 (some based on the knowledge it's designed to be like a 24AW). PTxx mps are starting to become more popular, mostly amongst college students where they have to play in more things than bands.A fellow board member and player of fantastic banding pedigree uses an M Finn mp. He makes a great sound and uses BBb in smaller groups too, blending really well - although he does play bass trombone so I'm not sure you could count him as a proper player

Sorry Andy.
In 1988 I flirted with a Schilke 67 and a PT90 in some serious banding action but neither helped, in fact exactly the opposite, me to blend with the rest of the section so exotic mps have been around here in the UK for a long time but in the banding world have never taken off.
Perhaps the blending is the main reason the 24AW is so popular. In a banding bass section we need to provide a sound more akin to that of an organ pedal than the lower range of a grand piano - same octave but totally different timbre - to fit in with the mainly conical instrumentation. In an orchestra we're either with the cylindrical trombones or the (cylindrical) horns so the fat organ sound isn't suitable here; in a brass quintet the difference in sound requirement is even more marked.
Personally I don't believe that there is a better brass band orientated mouthpiece than the 24AW but can understand why it doesn't work for lots of other people in different ensembles.
I'm very much looking forward to trying out the Imperial + #2 in quintet, 10 piece and orchestra over the next 4/5 weeks - was asked to play with Grimethorpe on Saturday but have an orchestral workshop with young kids to do - on Dvorak New World Symphony. I wonder what mouthpiece is best for those 8(?) notes? Oooh, I can feel another thread coming on.......
