Hey Chuck,
Thanks for explaining.
As for cutting, Why does it need to be CC to be an orchestra horn? Did some one make a law I did not hear about?:? If it is a great BBb, converting to a CC will most probably deliver an okay or so-so CC at best, it is simply not worth the risk, in my opinion. Besids, Ther are plenty of works that lay on the BBb with ease, and a pro should be able to transpose with no problem, come on boys suck it up and deal!
I have had opportunities to play a number of cut horns and not one of them could hold a candle to my good ol HB-2P or Tony's BBb 345 Holton or even the BBb 6/4 York I reconfigured for a now retired orchestra player some time ago. I am sure Mr. Rusk has delivered some decent cut horns but to date I have not seen or played one that (in my opinion) was worth the risk. And with the old BBb 6/4 instrumets available going for much higher prices, I feel it is more sensible to leave them in BBb for those players looking for a nice orchestral quality American style, front action, .750 bore, 6/4 BBb,(breathe) which are almost impossible to find these days new, unless you can find a manufacturer in Europe that will build you one $$$$$$$$$$$$$$$. You want a 6/4 CC that plays fantastic and is in tune and does all the things you need as a player? Simple, pick up the phone and order one. You play BBb? oh, sorry, we don't make those in 6/4.

I have a line of folks looking for just that type of horn.
To some it may be nice to know that I have a number of folks waiting for there old Holtons and Yorks to be rebuilt and or converted, all staying in BBb of corse.
Been a long day, Its late, I'm tired, Time to shut down and go home.
