MM to MC back to MM

Even though many MM cartridges do not exhibit the typical rising high-frequency curve of many MC cartridges (and so sound [generally] more naturally balanced), I can't go back to MM, because I find that good MC cartridges seem to offer greater speed and dynamics, which I favor.

Once upon a time I had an Ortofon MC, and then I had several Signet cartridges. Every time I needed a stylus replacement I found out that my model was no longer supported, but they would make me this real good deal on a new one that only cost, (before discount) 50 percent more than my cartridge. It took three times, but I finally realized the game they were playing. So I bought a Shure V15mr, and lived happily ever after.

I have gone back to MM because I have decided that not only MM's are better for now,but(wait for it) so are conical styli.Firstly as part of an exchange with the ex-reviewer Martin Colloms he mentioned the fact that MC's pass a lot of high frequency artefacts that MM's filter out naturally. I noticed that with the Ortofon VMS 20 a spherical tip replacement stylus sounded better than the original elliptical.Then at VA I found this relating to an old Fulton Musical Industries cartridge.
"Fulton elected to use a spherical tip because they believe that both elliptical and Shibata shape styli are subject to forces that twist them as they pass over modulated groove walls. Further, this twisting motion of the stylus is transmitted down the cantilever and is reproduced as distortion by the phono cartridge. There is much less extraneous torquing of the cantilever by its stylus with a conical tip. At 5kHz Fulton engineers have measured three times the distortion with elliptical and Shibata styli than with a conical. Accordingly, the tendency of an elliptical or Shibata stylus to twist or torque indicates that the nuances of music are lost and, at the same time, distortion in the critical 2 to 9 kHz frequency range is added. A conical tip apparently sidesteps this problem." I also think Moving-Iron can be superior to both MM and MC.The Ortofon is a MI.
