Blending Blumlein and ORTF Choirs

I'm preparing my mix's for the choirs I just finished recording.

2 DPA 4011A in ORTF
1 Royer SF24 in Blumlein
1 Audix M1280 micro condenser for added detail

Any suggestions of how you blend blumlein and ORTF?

John, did I hear you right... choose which of the two that sounds (fullest, widest most detailed) and add the other to taste?

ORTF

The ORTF stereo technique provides the recording with a wider stereo image than XY stereo and still preserves a reasonable amount of mono-information. Care must be taken when using this technique at larger distances, as the directional microphones exhibit proximity effect and will result in low frequency loss. You could add low frequency with an Equaliser to desired taste.
