I will echo everything you said about the MF4. It produces a noticeably more colorful and focused sound on my B&S than the PT-64, which is the gold standard for that instrument.

And I thought as you did, that the MF2 might be just the ticket for the bigger instruments. I found a used one and bought it, but frankly the result wasn't as good compared to the mouthpieces I was already using.

On my big tuba, I use a PT-48, which is supposedly a Helleberg shape but which I notice is decidedly more bowl-shaped than an actual Helleberg. It makes a much more colorful and focused sound on the bit tuba, and is an excellent woof preventative. For an instrument that tends to the dark, the PT-48 might be a worthy contender. On a Miraphone, though, it can hurt people.

Don't you think this would be just a little too easy?

On the contrary, the best description of interior shape and rim profile of any mouthpiece maker!

A little out of date, though - no coverage on the MF 5 - but it does show how different the MF 2 is from the MF 4.
