There has been a good and confusing discussion on one of the marketers list recently asking which is supposed to be used spf1? or spf2?
I have always just had people publish an spf1 records for the domains in the return-path (bounce) and FROM (pretty) address and have had nothing negative come of it.
My good friend Matt Vernhout from Thindata posted this to his blog today

SPF2 is alive and kicking, but yes, you can use SPF1 records as an entirely safe fallback that is checked more ubiquitously.
As I said on Matt's blog, even the SenderID cache site asks for SPF1 records:
