However, I think that the balance is more important than the weight in affecting how comfortable the flute is to play. A top-heavy flute just feels all wrong.
You’re right, of course, David!
Just look at the unpopular Patent Head of Rudal and Rose.
Wonderfully sound engineering…way-cool design…but heavy to the point of distraction for some players, but not all.
Several great players – Frankie Gavin on his flute album is holding and played a Patent Head Rudall, as does Frank Claudy and, I believe, the original photo of the album (the vinyl one) for Michael Flatley.
I can’t play one without wrist problems after many hours, so I had a separate modern headpiece made for my Rudall.
