+1 to Bloke...
I also use F for Meistersinger, and performed it a couple months ago on it. It's not a dominant part, and the trill is much cleaner - IMHO - on an F... here's a trick to try, BTW - pull your fifth (if a flat whole tone) out about another 1/8 tone (on my 621, all the way to the bell), then trill with the thumb... works on some CCs as well without the pull
Ron Bishop - IIRC - used a 184 on their last recording of it (2001?). It is so perfect, musical, and balanced it makes you cry... and contemplate throwing your instrument under a bus!
I like Yasuhito's approach in general; he uses BBb quite often, Yorkbrunner for his workhorse, and F more frequently than most... and he sounds glorious on that F!
