Comfortable fingering? Rachmaninoff's Op. 32 No. 10

[fmiller]

Hi there,
I started learning Rachmaninoff's Prelude 10 from Op. 32 about two weeks ago. It's quite comfortable to play, but I just can't find a comfortable fingering for the cadenza.

I have found multiple fingerings, but I can't find a comfortable one.
These are the ones I found:
2-3-5-1-2-3-1-2-3-5-3-2-5-2-1-3-2-1 (given in the sheet)
When I play this fingering, I always 'loose' the lower F sharp because of the weird twisting I have to do in order to get my middle finger on the b.
2-1-2-1-2-3-1-2-3-5-3-2-5-2-1-3-2-1
This is way more comfortable than the first one, but I can't get it up to speed, because of the crossing over of my index finger.
1-2-5-1-2-3-1-2-3-5-3-2-5-2-1-5-4-2
This one is also way more comfortable than the first one.

I'm not really sure which one to use. So, What did/would you use?
Thanks F.

Learn the concept of note grouping.  If you are fingering individually, it's most likely wrong.
