CTB Source Four 750 to Match MSD 250/2

I have a director who wants me to match a special (Source Four running a 120v 750w lamp) with our Design Spots, which use an MSD 250 lamp. My ol' standby of using R60 just isn't quite cutting it - it looks a bit green by comparison.

The MSD specs seem to state that they run at around 8100K. What level of CTB would you recommend for at least getting close to this color temperature?
 
To get the best match you are going to need to layer up a few CTBs (I think Rosco makes 1/3 as well as the more standard 1/2) with some minus green (or a very pale pink). Do note that the fixtures outputed CCT is usually significantly lower then the CCT listed in the lamps specs (often by a difference of over 1000K).

Would any of our more film focused folks care to offer more specifics? (I'm sure Ron is busy thinking up who to summon).
