jumping in here, yes, there are 2 fingerings for C#, plus the C# trill (little key just under A tonehole) which also works for High C# when fingering B
<<It's definitely me>>
perhaps check out air pressure and lip rollover?
test to see if you can do octave leaps and drops from low D to top D (the one usually played half-hole) -- but don't open the half-hole -- do it by overblowing -- combination of more focused air push and more pin-hole of the tip aperture should do it
of course it's all very subtle and it isn't a supreme effort, High C#, D and Eb are really as easy as High C
work Top C#, D and Eb on overblow (and relax again to normal blow for the drops) and do all that a few times until you've got the feel of it -- that's an illustration of the air pressure needed to maintain High notes
it could be the reed -- not strong enough in high partials -- but first start by addressing a common problem, not enough roll-over to shorten the reed fibres at the reed's best spot, basic physics, shorten a vibrating string at half stop, get octave
good luck going higher than you've ever gone before
... out of curiosity, talking of optional fingerings, my Rubank chart shows optional top C-natural fingering (not High C) as oXo/ooo but all i get is a very stuffy duff bleah -- does this optional fingering actually work on any of your capped instruments out there, including E-horn, or maybe it only works on ring-keys?
