The XT-2's Provia sim is stronger in the cyans than the XT-1's but I like it.

Pro Neg Standard will possibly be my colour go-to if shooting "to raw": it's a little flatter and more neutral, so lends itself well to post-processing.
That said, the onboard jpeg engine, raw conversion and film simulations are so blindingly good that I'd get the shooting done right at the front end if I were you, then shoot RAW + FINE onto 2 cards. You only need to output the raws at their Silkypix defaults then.

IT IS POINTLESS to shoot a crap shot on the grounds of "shooting raw so as to add in post": see the shot, expose for it, take it and be a photographer, not a bloody data-capturerer!
