scriabin op 42 no 6 fingering advice

[pjaul]

What fingering would you use in the right hand for this figuration?  The piece is Scriabin Etude in d flat major Op 42 no 6.

I have been using:   [ 5 3/1 2 1 2 ] [5 3/1 2 1 2 ] [ x 5/2 4 1 2 (5)]   for the first measure.

I'm concerned about what will work the best at a fast tempo.  I would appreciated anyone's insight.

I hate to be that person who comments on their own original post, but I really am wondering if anyone has played this piece or has an enlightened idea for fingering.  If no one replies I swear I'll let it go.
