I worked as a full-time professional cellist in opera and symphony orchestras, and the violinists would often bemoan the ridiculous number of ledger lines. So I'm just repeating what they indicated. Speaking for myself, I would much rather have an 8va indication than lengthy excursions into multiple ledger line land, except for brief passages. (But we cellists have the advantage of both tenor and even treble clef, which pretty much ensures that you can stay mostly "on-staff".)
Here are a couple of typical rapid passages that I remember the violinists complaining about. The Dvorak doesn't use an 8va, and the Dukas does. To my mind the latter is easier to read. But I will stop posting to this thread at this point as I fear that I am pulling it off topic in a direction away from piano notation!
