waltmon, absolutely any Colette-series capsule (MK anything) works with the CMC 6 amplifier (body). That includes MK 2, MK 2H, MK 2S, MK 3, MK 4, MK 40, MK 41, MK 5, MK 6, MK 8 and quite a few others, including the BLM 3 and BLM 03 C boundary layer capsules.
The Schoeps MK 41 has a directional pattern that is somewhere between being supercardioid and hypercardioid. When the MK 41 design was introduced as part of the vacuum-tube M 221 B series in the 1960s, it was called the MK 241 and its pattern was a little more toward hypercardioid than it is today. Consultation with users resulted in a shift during the early 1970s more in the supercardioid direction. The main difference is, "where's the null angle?". It's a little farther back on a supercardioid, but closer to the side on a true hypercardioid.
Schoeps always used to call the MK 241 a hypercardioid capsule, and continued to do so for a little while after they adjusted the design (by then it was the MK 41 capsule of the solid-state CMT series), but then their U.S. rep at the time (Posthorn Recordings) decided to start calling it a supercardioid, and then Schoeps themselves decided to go along with that.
True hypercardioid microphones are quite rare. Look at the polar diagram for the Neumann KM 150 or KM 185, for example, which is listed as a "hypercardioid"--it, too, is somewhere between supercardioid and hypercardioid, and slightly closer to supercardioid if I recall correctly. The same is true of the "hypercardioid" setting of their U 89, TLM 170, USM 69 and TLM 127 microphones. The same is true if Sennheiser's MKH-series "hypercardioid" and Beyer's "hypercardioid" ribbons (the M 160 and M 260). All these microphones are somewhere in between--most being closer to supercardioid.
