What piece should I learn next

[sonata_5]

I wanted to take on a little “rogue” project outside of normal practice and I  wanted some recommendations because I am very indecisive. I want a challenge but not as difficult as the pieces I have done below.
Some repertoire that I have got to a very good level are the Chopin etudes op 10 no 9 and 25 no 2,the last Bulgarian rhythm from bartok mikrokosmos book six and am currently working on Chopin op 10 no 5. Thanks!

This post was a while ago - did you pick a rogue piece?

You played Bartok DBR no 6 - - have you looked at no 1?  I think it's a more complex, richer piece than #6 - - very rewarding to study and play.  I've played all six, No 4 is really enjoyable to play too.

Bartok Allegro Barbaro would be fun to play, too.

Actually,I was planning to do Brahms ballade 4 or 1.Is that a good idea? And which to start with?
