While the RCA 77's were decent, they never came close to the 44's which could grow agates on a soprano. But try to find one with the ribbon in decent shape!
I'm using a Sennheiser MD441 in my own studio and put one in a station's somewhat noisy production room for the same reasons; the very tight pattern that eliminates noise off to the sides and for the flexibility with the adjustable response curve. Doggone things are antique; you'll see earlier versions in World War II film clips when German "Party" bigwigs are speechifying.
