Has Anyone Tried The Mike Finn "H" Mouthpiece

I was wondering who has tried the Mike Finn "H" Mouthpiece. And what you think about it.

I had one for about a year. I loved it, but the throat was too large for my tastes. If I could get that same exact rim on my blokepieces, I would be in heaven.

I used to have one... really nice mouthpiece, but the rim diameter was just too small for me.

Its a phenomenal sousaphone mouthpiece.
