CONN Curved Sop/what a MPC?

hi people,

I know, there are a lot of threads out there and I read all what I can find , however...

I bought just some days ago my first Soprano a CONN curved 1925 and I expect to face difficulties at the beginning.(this is normal, is ok)
I am looking for a good MPC to match and to play it in tune. My tenor and alto and my C melody (all 20`s CONNs) demands large Chamber Mouthpieces.
For tenor I have a Link custom, for alto and C mel a Morgan and for soprano...?:?

thanks for your recommendations...
