I think that this is a great selection of repertoire for auditions - it may be too much, but this is not a bad problem to have. If I were in your shoes, I would make a choice between the Chopin scherzo and the Liszt; I myself would use the Liszt. The Liszt is a good opportunity to convey knowledge of opera and of orchestral sound (in addition to the inherent virtuosity). Did you know that Rigoletto will be on the 2007-2008 opera season at IU?Best,Michael
