F# minor Novelletten Op 21 no 8 is the one to go for. i did some serious and mostly enjoyable work on it a year or 2 ago. ultimately disappointed that i never got it the whole way through to the 'play to my teacher' level. the best bits are brilliant but I'm not sure every bar is equally inspired. good luck
Thanks the first one is pretty straightforward, but I haven't looked at the others yet, will have ago at No 8 this evening
