yo lets do something else bra!
i know u posted the first 2 mvts here smoewhere, and i on dasdc in tha SHAGA masterclass, so if you really want we could analyze the 1st 2 mvts (although yours was much more polished/coherent/true than mine was
)
buti really dont think im up to relearning all 60 pages again 
but these duels are great motivation for learning pieces and learning from others
Okay

Do you have a suggestion? To me it would need to be something completely new (but maybe with a generous deadline like dec. 31st because I am very busy with "Styx. A long Journey" mainly, over the next few months), something deep, existential, not well-known, virtuoso and not very long.

Yes I get quite pretentious, sorry

The reason is that I still have to fight with dystonia (though it got better) and can only do very few, important things.
