The ORTF arrangement is a wonderful general pickup, especially for small ensembles. I have always been aggravated by the the limited low end of the directional mics required in an ORTF, but you can use a good omni pair (such as the Schoeps MK2 series or DPA 4006) with acoustical directional accessories (a 30mm slip on “ball”) to give you the required directionality yet preserve the marvelous low end of a good omni. Since the Neumann TLM-50 is now a “legacy” item, the Schoeps and DPAs with the spheres can work very well in place of them.
