Hi IgnazPaderewski,
Practice the piece phrase by phrase, variation by variation, using Liszt's 24-24 . . . fingering if you feel you can handle it. It adds more power and fire to the galloping horse behind Mazeppa's story. Otherwise many people adopt the facilitated 24-13(LH), 13-24(RH), 24-13(LH crossing over RH) approach, which is still quite difficult.
By all mean, master both sets of fingerings.
And curiously how many people stick to the Liszt fingering?
