Chopin Nocturne op 72 no. 1

[guitarwolf]

I have a question about the big trill in this piece. 3rd page 8th bar. I know the first part of the trill is with the 1st and 3rd finger. My question is when you switch over to the latter part of the trill what fingers do you use? I land in the position that would leave me using my 3rd and 4th fingers to trill but I cant trill nearly as fast with those like my 2nd and 3rd. Can any of you trill that fast with your 3rd and 4th? I do a quick switch currently and use my 2nd and 3rd after landing on my 4th finger. It goes 2 1 3 4 then my 2nd comes down for the trill. Is that what your supposed to do or do I need ALOT of trill practice with my other finger?

First of all Guitarwolf, depending on the edition of your nocturned, the 8th measure of the 3rd page is going to vary, but I'm assuming you mean the first trill.  I think I've used 1313 for the grace notes because this is the strongest motion.
