Northwestern Audition

[bluessax576]

Hello, I apologize for a post that happens all the time here, but, I need help with repetoire.  I am auditioning for Northwestern University (among others) this coming February.  My audition set includes:  Bach Prelude and Fugue in G Majore (Book 1)
              Mozart Sonata in C Major, K 330
              Medtner Fairy tale op 20 no 1
              And here is where I need help, I am working on Alkan's Aesop's Feast, but I am a little worried about having it performance ready by February (I'm pretty confident, but there are seven or eight of the variations, including part of the coda, that I am worried about), or, I could do Tchaikovsky's Doumka.  My issue with that is, will the Doumka show off enogh technique and stamina to impress the audition panel?  Any thoughts and/or comments about this would be greatly appreciated, thank you.
