It's all very well to have clear notation, but the editor has paid no regard to the turnovers. They are all hopeless. String players have a bow in one hand, and their instrument in the other. It's impossible to turn unless there is a suitable gap in the music. Too many people who transfer music to modern form from the original copy don't understand the need to put the turnovers in a suitable place, even if it means cramping up the notes, or using more pages. I don't think they've ever tried to play from the parts they've created. The actual music sounds fine!
