Thoughts on Oft mpc?

[Bach5G]

Any thoughts on the Griego-Oft mpcs? I had an early version that I liked but probably gave up on without giving it a proper shot.

I find it to favor efficiency and stability. It feels like something that would benefit a principal player when you play one. In my experience the alto mouthpiece only works on alto, it wasn't a good fit for valve trombone or small tenor.

Though it may not work well in small tenors, IMHO the alto mouthpiece is one of the best alto mouthpieces available...
