If you don't have problems with the left hands 5-4 finger stretch, the etude should not be of much problem at all.
yeah, i have luck that my hand is very VERY big, so fingering 5-4 is definitely not problem. bigger problem is quick switching from ff to pp subito, and those octave repetitions and quick thrills, but i find that more easier then before, when i was starting to learn this etude.anyway, thanx for advices!
