Gotta disagree, to some extent. It’s annoying as all getout to listeners when you’re constantly retuning, and if you’re playing advanced classical music you’re for sure going to run into situations where you need D#, unless you don’t play any pieces arranged by Americans.
I’d have to agree that with good levers four flats is a good tuning–I wish I’d gotten used to it early on, since it would make accompanying cantors at Jewish weddings infinitely simpler (f minor is a very standard key)–but it’s also visually confusing when you’re making fast lever changes and you’re used to seeing one thing then suddenly it’s different. And the harp isn’t pleased, either. It’s not going to stay perfectly in tune when you suddenly change the tuning.
