Is this an appropriate way to cheat?

I have rather large hands, so sometimes I like to use them to my advantage in the fingering of pieces. Right now, I'm attempting to learn the 3rd movement of moonlight sonata. On the beginning arpeggio where it calls for the 1235 1245 1245 I play it 1235 1235 1235. Is this okay with large hands or will it slow me down trying to get it up to speed? I started it yesterday so changing the fingering won't be a problem either way.

Either way is fine

Agreed.  Nothing wrong with that fingering. 

Some people are also more flexible, so using 1235 may work for them.

I always use that fingering, and I have small hands. Do what works for you
