@j_menz: my strongest, IMO, is the ravel and beethoven, second strongest liszt, weakest messiaen. starting with liszt doesn't seem like a good idea though...
I'm pretty sure programs are supposed to be from more substantial to less. Based on that, i'd say:1.Beethoven2. Ravel3. Liszt4. Messiaen- not sure about this one, i'm not familiar with it.
