Casey Burns Bb in Mopane or Blackwood?

Has anyone ever tried a Casey Burns Bb flute in either wood? Do you know if they come with silver rings or not?

I haven’t but you might check the website.
There appears to be no tuning slide.

Just talked to Casey, a very nice fellow.
The Bb flute comes without rings, though he will
make you one with them if you wish.

Also he suggested to me a mopane body
with a blackwood head joint. Says it will
sound better than an all mopane flute.

Also he can make 'em with keys
and has a picture of one of these on
his website. Best
