Also have a look at Op.25/6 and 25/10, which are easier than Op.10/2
I am working on both 25/6 and 10/2.10/2 is a walk in the park compared to 25/6.
Not for me. I am not saying I can play either one of these etudes, but playing that chromatic scale with my weakest fingers(3,4 and 5) is my nightmare. Not saying 25/6 is not hard, but Op.10/2 looks scarier to me.
IMO Winter wind is a piece that isn't terribly difficult mechanically to play; it's real difficulty lies in balance and making it sound as if it's the easiest thing in the world. The sextuplets really aren't hard, but the natural tendency is to display the showy bit while letting the theme just kind of turn to mush.As for the next etude, I'd also cast my vote for Op. 10 #4. Though, if your LH is weak, definitely consider Op. 10 #9.
You can play winter wind and Op.58 mvt 4?? How is it going?
I knew this topic would eventually turn into "which one is harder" showdown. lol
