No need to flash firmware first, I went straight from crdroid and it works, but don't forget to wipe dalvik, cache, and data before flashing project elixir. Also format data. Here's a guide: https://github.com/ProjectElixir-Devices/Wiki/blob/snow/surya.mdApologies for the silly question but do you only need to flash the ROM or do you need to flash firmware first? Currently using pixel experience as the ROM was all you needed. This looks great but the way!
