Isn't ORTF a horizontal configuration? How would you make it an overhead?
I believe that ORTF just refers to the angle of incidence between the two mics......not that they have to be horizontal (they just have to be on the same "plane"). the point of ORTF is to mimic what your ears hear.
FWIW, in my mind's eye, i read the subject of this thread at "OH's....A/B, X/Y, WTF?"....which i think would be even better.
the differences in the miking patterns is simply going to be what you pickup and where the various pieces of the drumkit "live" in the spectrum....how wide the pickup, etc.
personally, i prefer a spaced pair which balances the kit....rather than a strict XY, ORTF, etc., positioning. i put the "left" mic so that it best represents the left side of the kit and the "right" mic where it best represents the right side of the kit, and make sure the "middle" overlaps. with spaced pairs, always be sure to check for phase problems.
and honestly, lately i've been getting a LOT of enjoyment out of a mono overhead. i'll put the stereo pair out in the room.
cheers,
