I can't decide the best thing to do with the ledger lines above the bass staff (see attached image). The arpeggios start well in the bass clef, then extend more than four ledger lines above, then start low again. If I write it in treble clef, then I end up four ledger lines below, or I'd have to have a clef change in every measure (which seems just as awkward). I'd like to try to avoid all these ledger lines if possible, but can't think of a good way to do it. Any suggestions? Thanks!
