I don't use references, unless I am mastering (which is simply for RMS levels).
Why mix to a reference which has been mastered? The sonics can be vastly different - so, as I see it, there's very little point in trying to mix something against a reference.
Each band is different - and unless they're a dead replica (eg: AC/DC & Airbourne) then I'm never going to try and match the dynamics and sound of a record.
I make records that sound like they're done by me (for better or worse).
