OK...so here's the next step. How about the MK41V > m222 > NT 222 stuff?
Love the sound of the M222/NT222. Not sure the MK41Vs are worth the extra cost over the MK41s.
Seems like a lot of questions without much discussion about your situation, goals, etc. What's your budget? How much stuff are you willing / able to schlep around? What do you plan on recording (e.g. amplified rock, unamplified bluegrass, unamplified strings, etc.), in what environments (bars, amphitheatres, performance halls?), from what positions (on-stage, up front, tapers section, studio), and in what general configurations (2-ch, 4-ch, multitrack, etc.)? What general "sound" do you like? Are these replacements for the KM140s / U89s / 4022s in your sig, or additions to the stable?
Lots of people make good recordings with Schoeps (or insert X brand here) gear. Lots of people make poor recordings with Schoeps (or insert X brand here) gear. The question is: what's going to be best for your particular situation, budget, goals, etc.
