Fingering Rachmaninoff sonata 2 movement 2

[tenpasten]

Hello, I am wondering about what fingering I should use for the fast sextuplets in this section. I use 543212 at the minute but see others doing 545321. This is very uncomfortable for me and I can’t seem to get it up to speed. (Sorry for the blurry photo)

I use 154542 154542 but have never tried these alternatives.

I think a thumb on the beat is useful to maximise loudness and emphasise the beat with the LH? To me this passage should be thunderous - all the bells tolling together.

I am more concerned with what your back is doing - giving it all you've got?

You mean you can;t play it like this:

i=xlPSg1C1NLLPhleO

or even this?

Break a string.

Some of Horowitz's notes are correct, some are even in the right order, but the overall impression is tremendous.
