fingering for Rachmaninoff Prelude

[liszmaninopin]

I am in the process of learning Rachmaninoff's Prelude op. 23 #5.  Can anyone suggest a particularly efficient fingering in the left hand of the middle section?  I have created a usable fingering pattern, but it isn't really comfortable and wonder if there might be something better.

What is your fingering? Try 5-2-1-5-3-2-1 on the first arpeggio and see if that works, the rest can be fingered similarly.
