Bari Raptor?

So....I found one for sale pretty cheap.
It is heavy and thick.
I can say as advertised...it plays easy in all registers loud and soft.

It can get very bright. It sounds ‘wide’ if that makes any sense.
I haven’t put a pad on it yet. The texture feels a little rough on my teeth without one.
It’s a fun mouthpiece

I am going to do some recording with this today.
I tried to use it on a session a few days ago that was a mello sectional thing...it was bright and loud. switched back to Otto Tone Edge.
Tracks I ma working on today are punchy funk. Should be great for that

Are there theories about mouthpiece weight?
