I use 123512345 and it works fine. For the stretch on the 2nd half, you have to let the arm and wrist carry the hand over....so there is in fact very little stretch if you do this correctly. You just stay on top of the keys and go over like an arch. You get more power this way, which is what you need as you use 45 of the LH.
.
But if you take the RH E's with the LH in the next passage you break the legato between the voices in the LH. This cannot be done, it must be legato, as you have to get the RH really clean and not heavily pedalled.
Just finger the RH 1 2 3 5 4 1 2 3 5 4 3 2 1 2 3 4 etc.....The 5 over 5 may seem strange, but it works perfectly. If you have studied op10no2 Chopin, this fingering is not a problem at all. This is a hard passage, and takes some time to master. Practice hands seperatly a lot, and look for the most efficient movements.
If you try to play these first few pages with only the fingers, you will fail miserably. It is very stretchy, and has a lot of big arpeggios that cannot be played legato, but must be played legato.
The section I find most difficult in this piece are the 8 bars before the presto near the end. They require a lot of power, especially in the LH, and it is very fast, so you don't have much time to get to the bottom of the key. Then when you do generate the power to do it, you have the presto and the prestissimo to play, which is really tiring after 27 minutes or whatever of playing before! This ocatave passage only becomes really hard when you play the whole thing through under pressure. It is hard to begin with....but if you are playing this piece and plan to perform it, I highly recommend you play this passage everyday for some time, just to build up the strength. Especially the LH octaves.
