Hey Shortfingers! I just got your message today (I only visit the forum about once every two weeks haha).
As mentioned previously, splitting the arpeggios between the hands is MUCH easier. If you listen to some recordings, the give themselves a bit of space to play these... the arpeggio is 'before' the beat on paper, but if you don't give yourself a fraction of a beat to play it, it'll just sound like a chunk of fast notes. They're fast, but still need to be clear. So, practice it slow with two hands (you'll soon realize it is MUCH more manageable this way).
