Interesting thread. Thanks, Fred, for your example. The differences are indeed there but surprisingly minimal.
As per winged repeats: I’ve realised how nonsensical my own reaction to them is. I’ve always had a kind of antipathy to them simply because I never see them in the printed music I’ve always used, but when I look through my own scores, most non-obvious repeats have wings which I’ve pencilled-in. It’s never too late to change one’s opinions!
